E3E4 E5 Numbering, from 000 to 999

There are no generally valid rules for numbering. The numbering must follow the process and not

the point of installation. For example, where a number of alarm lamps for a power supply of a

pump unit are needed in different installation units (on console, electronic module, switchgear

truck), each is to be numbered under the process related code of the pump unit.

Example 2: Identification of components within components

LAC10AP100-M01 = Feed water pump nr 1 motor

5 ELECTRICAL AND C&I IDENTIFICATION Two types of code are necessary for identification of electrical and C&I and functions, as follows:

Process related code: Identification of electrical and C&I equipment and functions, for example, power transmission,

switchgear, transformers, unit protection, functional group control.

Point of installation code: For the unique addressing of the points of installation of electrical and C&I components, for example, in

control consoles, panels, cubicles and cabinets.

In addition to these two types of identification for which the KKS establishes rules, the following codes

are necessary :

Connection Code When the KKS rules be inadequate it can be used the DIN 40719 Part 2 for connections to identification

of installation units, installation spaces and components. The DIN mask is as follow:

Installation Unit Code Installation space Code N A A A N N A N1 ... N8 Max 8 data characters

This code should start with an alpha character.

Cable Code For the identification of cables and wires.

Cable Conduit Code For the identification of cable conduits.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 18 / 74

5.1 Process related identification The format is as follows:

Plant Unit

(0) System Code

(1) Equipment Code

(2) Component Code


B C0 C1 C2 C3 - according to 3.1.1

C4 C5 This is a numeric code number that is agree during the project. The principles are the

following:

Starts anew when the preceding classifying code element changes; Numbering may be consecutive or grouping; Numbering need to be continuous; Numbering convections, once established, may not be altered; The possibility of later addition to the system should be considered.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 19 / 74

5.2 Point of installation Identification The format is as follows:

Plant Unit


(1) Installation space code

(2) B C0 C1 C2 C3 C4 C5 D1 D2 D3 D4 D5 D6


1 = Plant Unit 1,

2 = Plant Unit 2,

3 = Plant Unit 3




C0 Level 0 (Special number to identify System code with the same function reserved field take the value 0)

Examples:

10 = unit 1 equipment

A0 = common equipment to 1-2 units (for example, demineralised water)

90 = common equipment to the plant (for examples, demineralised plant , coal

transport)

C1 C2 C3 Level 1 (Installation unit Code) Example LV switchgear

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 20 / 74

C4 C5 Level 1 (Installation unit number)

D1D2 Level 2 (Installation space code) There are possible methods of installation space identification:

No subdivision into installation spaces, e.g. 10 kV cubicles. In this case dont use the Level 2.

Subdivision into installation spaces. This correspond to the layout that it was assumed. In this case, D1D2 gives the vertical subdivision (rows) and D3D4 D5 gives the horizontal

subdivision (columns).

The rules that must be applied are:

Direction and sequence of numbered The left to the right and the Top to the bottom. Additional data may be necessary and in this case we can use coordinate grids to provide

unique identification.

In case of miniature hardware systems we can fix

subdivision with coordinate grids. The top left hand

corner is used to give the reference of the

component.

If it is necessary to create additional fittings

referenced to the grid, numbering starts from the coordinate system origin of the prescribed grid,

proceeding in descending order from 1000, against

the direction of numbering.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 21 / 74

If it is necessary to create additional fittings not referenced to the grid, installation zones are identified with first letter of breakdown Level 2.

Subdivision without fixed coordinates. The rules

described above are applied.

This can be identified by the near row letter or by a

sequential numbering.

D3D4 D5 Installation space code (Horizontal subdivision-columns of installation spaces in installation units)

D6 Additional code for subdivision of Level 2.

Sometimes, in electrical cabinets it is necessary

to identify components in depth. In this case we

can use the letter E with combination with

numbering and letters.

In C&I, the rules for identifying cabinets are the same as switchboards. For control stations and

control room desks we can use the following procedure:

Create a horizontal and vertical grid starting at AA000 (left hand corner). The area cover different orientations, e.g. from vertical to angled as with the transition from

vertical panel to inclined board.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 22 / 74

27 = terminal block no 27

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 25 / 74

5.4 Cable Identification The cable identification includes a classifying and a numbered code element. The process-related or point of installation code is used in part or in full for a classifying element, with the code of the two cable ends which come first in the alphabet generally being adopted for the

classifying element of the cable code. The numbering element of the cable n consists of 4 or 3

numeric and 1 alphabetic data character. The mask is as follows:

Classifying Element Numbering Element

Process-related Code (see 3.1.1) Number

Plant Unit

(0) System Code

(1) Equipment Unit Code

(2)

B C0 C1 C2 C3 C4 C5 D1 D2 D3 D4 D5 D6 N N N A/N

Or

Point of installation Code Number

Plant Unit

(0) Installation location code


(2)

B C0 C1 C2 C3 C4 C5 D1 D2 D3 D4 D5 D6 N N N A/N

In general the cables are identified with the code of the cable destination which is first in

alphabetic order. The numbering element of the cable no comprises four numeric data characters

or three numeric and one alfa data character. The numeric data characters may be used four

grouping within the cable no; when it is necessary the alfa data character may serve to

distinguish parallel cables or application areas for example.

Grouping of the cable no is recommended in order to keep agreements on the allocation of cable

nos during planning to a minimum and to prevent multiple allocation of cable nos, e.g. group by

technical application areas, suppliers, etc. The first digit of the four numeric data characters

serves to identify the application area, the three other numeric data characters to number cables

within that area.

NNNN Application area

0--- Power cables > 1 kV

1--- Power cables 1 kV

2--- till 3--- C&I cables > 60 V

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 27 / 74

5.5 Cable Conduit Identification To identify the cable conduit we will go use the EDP specification based on the KKS installation

code with the following mask:

Plant Unit


(1) Conduit type code

(2) B C0 C1 C2 C3 C4 C5 D1 D2 D3 D4 D5 D6


1 = Plant Unit 1,

2 = Plant Unit 2,

3 = Plant Unit 3




C0 Level 0 (Special number to identify System code with the same function reserved field take the value 0)

Example:

10 = unit 1 equipment

C1 C2 C3 Level 1 (Installation unit Code) Example:

UMA= turbine housing

C4 C5 Level 1 subdivision

Example:

UMA01 = zone 1 of turbine housing

D1 D2 Level 2 (Conduit type)

We have the following conduits type:

EH = Horizontal conduit conduit in horizontal or non-vertical position

EV = Vertical Conduit conduit in vertical position

CI = Individual conduit conduit for one consumer derived of one general conduit. It

can be in a pipe, cable support or clamp iron.

CE = Exterior conduit conduit inside a concrete channel

CV = Burried conduit conduit in trench cable

T* = Tunnel conduit conduit inside concrete tunnel. The * can be the letters A, B,

C, and is used to do the subdivision of the tunnel in sections.

TE = crossing road when the conduit cross one road.

Example:

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 28 / 74

UBZ02TC = tunnel no 2, section C

D3 D4 D5 Level 2 Subdivision (Shelf)

It is a numeric field and have the following rules:

D3 - define the level/position of the shelf and increase from top to bottom (0 till 9);

D4 define the channel. The electrical philosophy concept is made in dual channel (A, B). This means that any dual equipment must have assigned one

dual conduit cable. In this way we increase the availability of the plant

because half of the plant is put out of service in case of a cable firing. For

example, each feedpump motor must be supplied by different conduit cable.

Then we will go use odd numbers for channel A and even numbers for

channel B. It assume the numbers :

o A = 1,3,5,7 and 9 o B = 2, 4, 6 and 8

When the equipment is not dual, for example, diesel engine, we will go use

for the cable the conduit that have less cables.

D5 sequential number of the main conduit or derivation. Assume the values 0 till 9.

The number remains unchanged when there is path changing except when occurs changing on the dimension, cross road or mounting type.

Example:

If the conduit UBA01EH110/B changes to vertical position the reference changes to

UBA01EV110/B. The reference gives the exactly path that conduit do.

There will be different numbers according to the voltage levels, e.g. power cables for medium and low voltage, cables for C&I and other cables

(telephone lines, intercom, etc).

Example:

UBZ02TC006 = tunnel no 2, section C, shelf no 6

D6 This character is to identify the conduit design voltage level. It takes the following letters:

A = Voltage level 60 V B = Voltage level > 60 V

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 29 / 74

C = Voltage level 1 kV AC (LV voltage including illumination) D = Voltage level > 1 kV AC E = Voltage level 1 kV AC (Batteries, rectifiers, emergency pumps) F = Telecommunication cables (telephones, intercom, etc)

When one conduit serves more then one voltage levels it must indicate all levels.

Examples:

UMA01EH110/B

UMA01EH210/B/E

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 30 / 74

6 LOCATION IDENTIFICATION See DIN 40719 Part 2 for all detailed description

Description of the levels:


1 = Plant Unit 1,

2 = Plant Unit 2,

3 = Plant Unit 3



9= Common to the Power Plant

C0 Level 0 (Special number to identify System code with the same function reserved field- now take 0)

C1 C2 C3 Level 1 (Structure code) - See the Level 1 KKS codes (Attached I). Examples:

UBA = Electrical Building

UBB = Building for general electrical services

UHA = Boiler House

UMA = Steam turbine building

URA = Cooling tower

UST = workshop building

UZT = Outside area

UYE = Gate house

C4 C5 Level 1 (Sub-system).

Examples:

Variant 1 : each structure is considered individually. This means that the numbers dont correspond to the same level in all structures.

UHA07 = Boiler house level 7 (+17.60 m in the example)

UMA03 = Steam turbine level 3 (+3.00 m in the example)

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 31 / 74

Variant 2 : each structure is considered global and there is the floor numbering. The lower level can start with the number 02 to introduce after during the planning the 01 for pump pits. The

floors, platforms receive even numbers and the intermediate floors and platforms receive the odd

numbers.



N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 32 / 74

Variant 3 : each structure is considered global and the objective is identifying floors at comparable elevations with the same floors numbers. The numbering start with 02 for the

lowermost floor of the power station. Further the floors number are determined by the ground

floors at station grade level, the control room, burner levels, etc. The structure having the

smallest spacing between levels governs the sequence of numbering.



Variant 4 : each structure is considered global and the correlation between floor numbers and ranges of elevations are agree before start the identification.



N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 33 / 74

D1D2 Level 2 (Room code) D1 =

R Room (may be omitted if code remains unique)

S Fire area (must always be written)

D2 = is not used in numbered room codes but we can use to number the outside areas. In this

case it take the letters A, B, .

Example : UZT 00 RA 615 = Outside area UZT nr 00, nr A, abscissa 6 and ordinate 15.

D3D4 D5 Sequential number of 000 up to 999 or 100s or 10s grouping. The numbering can be governed

7 EXAMPLES IN POWER TRANSMISSION For power transmission is recommended to follow the rules:

Numbering in groups of ten Starting from generator neutral 90s numbering for generator leads ventilation system

Example 1 - Single Line diagram

Use the following rules for transformers:

BA for generator transformers, BC for start-up transformers, direction of energy flow. Cooling for transformers under group B, water cooling under P, Fire fighting under S,

stationary fire protection under SG.

The windings of transformers are identified in the equipment unit code with GT for transformer equipment and numbered in D3D4D5 starting from high voltage side.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 38 / 74

Example 4 Windings identification

Example 5 Auxiliary power supply (switchgear, batteries, battery chargers, inverters)

These units are classified, depending on their locations, in the alpha element of

breakdown level 1 and numbered in the numeric element as units (cubicles, rows,etc).

normally the C1C2C3 of Point of installation Identification are sufficient.

The batteries for equal voltage levels and for the same tasks may be numbered in

C1C2C3 of Point of installation Identification. The method of numbering must be agree during the project (C4C5).

Example 6 Emergency generating sets (Diesel)

This is classified under BRV group. Because this group is limited we must use the X

group that gives more definition.

The Cubicle 4 = XKA01GS001+BDC04

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 40 / 74

Example 7 Incoming Feeders and Tie Feeders for auxiliary power supply

The classification is based on the destination principle, i.e. outgoing, incoming and tie

feeders receive the process related code of the recipient.

Cubicle 3 of unit1 plant:

Process related code = 10BHT30GT001

Point of installation +BBC03

Cubicle 2 of unit 1 plant:

Process related code = 10BHT30GT002

Point of installation +BHC02

Note:

Transformer code:

High Voltage = GT001

Low Voltage = GT002

Example 8 Cubicles for auxiliary buses

The cubicles receive the code of the transformer.

Cubicle 2 of BBE = BBA00GS001+BBE02

Cubicle 1 of BCA = BBA00GS002+BCA01

Disadvantage : Destination not immediately apparent (cubicle not indicated)

Variant 2 Addition of actual cubicle no of destination in C1C2C3.

Cubicle 2 of BBE = BBA04+BBE02

Cubicle 1 of BCA = BBA07+BCA01

Disadvantage : Dependence in planning on destination and therefore susceptible to

change.

8 EXAMPLES IN IDENTIFICATION OF C&I EQUIPMENT The C&I equipment is identified in the Function key in main groups C and D. The group D is reserved

and can be used if C and D is not sufficient.

The identification of C1C2C3 is made with the following principles:

According to subordinate control and instrumentation task, e.g. instrumentation, open loop control, closed loop control in separate cabinets.

o The majority of C2 coding letters of the main group C is allocated in accordance with this principle.

Cabinets containing a variety of equipment (hardwired instrumentation, open loop control, closed loop control together with the power unit in one cabinet).

o In this case identification is according to main C&I task on a priority basis. Structure according to overall C&I task for the process, e.g. functional complexes, unit coordination

level, process computer systems, reactor protection, programmable hardware systems.

o Certain groups within the main groups such as CJ for unit coordination level, CK for process computer systems, CL for reactor protection have been specified for this

purpose; groups CM-CT are freely available for system combination (e.g.

programmable hardware systems) and also main group D if groups CM-CT are

insufficient.

The data character C3 is unreserved for almost the entire group C for C&I equipment. Subdivision is

possible as required within the terms of stated definition.

Example 1 Available for subdivision

Local control station are assigned to CX. We can discriminate the Coal Power Plant

control stations as follow:

Coal supply system CXA Ash removal system CXB Cooling Water system CXC Diesel system CXD

Example 2 Power Supply, Ventilation and Monitoring cabinets

Every cabinet is identified on Level 1 and the Level 2 is used to increase the subdivision.

For example:

Power Supply GW Temp measurement circuit CT Cabinet fan AN Heat exchanger AC Electrical monitors, measuring circuits CE Position measurement CG

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 46 / 74

The Level 3 is used for lamps, pushbuttons, limit switches, etc according appendix 1.

Note 1) Multiple incoming feeders are numbered according 3.2 - example 12, e.g.

GW001A and GW001B. For this example we used the CCA03 cabinet.

Example 3 Peripheral equipment for information display and process control

Here is included information display and manual control equipment such as video display

units, multipoint selection switches, multiple recorders and release pushbuttons which

cannot be positively assigned to an equipment unit or a system. We use Level 2 to

identify these equipments and the following codes:

Multiple recorders, multipoint selection switches (for physically dissimilar variables)

CU

Release pushbuttons QS Peripherals for information display GK

The following rules apply to multiple recorders/multipoint selection switches:

Recording/measurement of identical physical variables from one system with one device.

In this case the indicator/recorder use the

KKS level 2 of the measurement and

level 3 starts with 9.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 47 / 74

Recording/measurement of dissimilar physical variables from one system with one device.

In this case the indicator/recorder use the

KKS level 2 of the measurement and

level 3 starts with CU.

Recording/measurement of dissimilar physical

variables from different systems with one

device.

When is used shared control and protection

equipment, we use for level 1 the letter Y. The

C&I which serves more then one main group

is identified under C group, e.g. control room

CWA.

Peripheral devices for information display This is the case of the process computer that

is identified by CKA and the level 3 by GK.

Example 4 Junction Boxes

On Level 1 the junction box receive the code of the structure and floor on which they are

installed. Exceptions are junction boxes for main machine sets/heavy machinery/electrical

and C&I cubicles and cabinets which receive the Level 1 of the associated main

machine/heavy machinery/cabinet.

On Level 2 we use the letter G in C1 and A-F in C2. It is possible to subdivide junction box

systems in C2 as appropriate to the plant configuration, e.g. separate junction box systems

for analog and binary transmitters. For example we use GA for binary signals connected to

the field, GB for binary not connected to the field and GP for lighting (see Attached 1).

The numbering is made separately on each floor.

A0UMA03GB004 Junction box for binary signals common to units 1+2 not connected to

the field nr 4 on 3rd floor of turbine housing

A0UMA02GP001 - Junction box for lightning nr 1 on 2rd floor of turbine housing common

to units 1+2

10MAC01GA001 Junction box for binary signals connected to the field nr 1 of LP turbine

1 of unit 1.

N. 1.2.060-PG-005-RL-2010 REV.: 1 FL.: 48 / 74

Example 5 Component identification for circuits connected to electrical junction box

To identify the circuits of one junction box we use on Level 2 the letter E followed by the

codes of the individual components in the circuit.

Example 6 Cable penetration

Cable penetrations into and inside structures do not receive separate code.

For electrical equipment such as transformers and generators they receive Level 2 equal

to GG.

Example 7 Transducer racks, supports and frames

This auxiliary equipment is identified like junction boxes on Level 1 and use GZ on Level 2.

A0UMA03GZ002 = transducer rack nr 2 on 3rd floor of turbine housing common to units

1+2.
