DESIGN OF ELECTRICAL POWER SUPPLY AND EARTHING SYST EM

1 Introduction This specification covers the basic technical requirements concerning the design and erection of the electrical power supply and earthing systems for electrical instruments, equipment and systems necessary in implementing the process control functions of installed facilities.

During the installation of a facility or plant the Project Specifications relating to the specific facility may include deviations from this document. In case of deviations the provisions in the Project Specification are applicable.

2 Deviations Project specification may include deviation from this specification. Any deviation from this specification & project specification allowed by written permit of MOL group only.

3 Applicable standards Unless other contractual provisions are used the design of the electrical power supply and the earthing system must comply with the relevant international and national standards, and with the regulations included in this specification.

When constructing an earthing system, with special regard to developing the signal ground systems, the documents and instructions of the equipment suppliers must always be taken into consideration.

Applicable standards: see MGS-M-REF-I-4 & MGS-S-REF-I-4.

4 Design principles for electrical power supply for process control systems 1. The power supply for electrical instruments, equipment and devices is taken from the electrical network of

the specific plant or facility.

2. For detailed description of UPS & their input, output distributors located in electrical area see MGS-M-REF-I-4 App & MGS-S-REF-I-4 App.

3. The power supply systems feeding the process control systems must have the same, or better, reliability indices as that of the supplied system from both safety and economic aspects.

4. In order to save the operability of the safety functions for the process control devices, equipment and instruments an uninterrupted power supply (UPS) with a 100 % redundancy shall be provided.

5. Amongst the UPS equipment batteries shall provide the required power. Change-over from grid to battery supply shall be an automatic process. The UPS must provide the electric power required for the emergency shutdown of the facility for at least a 30 minute time period.

6. Under normal operating conditions, and with proper maintenance the UPS must guarantee the 30 minute supply time for at least a 10 year time period.

7. The field equipment (instrument cabinets, enclosures) must have an isolating switch on the site.

8. Error signals from the power supply system must be displayed in the control room. The error signals must be connect with dedicated wiring and galvanic isolation.

9. The colour coding of wiring and lines inside the process control equipment must be uniformly designed in accordance with the voltage levels.

10. Failures of UPS located in electrical area shall be indicated in the plant DCS by the following way:

In general the UPS’s are operating unattended, thus a remote signal of the abnormal operating conditions must be given to a place where this information can be displayed, and action can be taken to remove (e.g. control room). As experienced displaying the following fault signals is justified:

UPS ERROR (common error)

UPS NETWORK ERROR (UPS battery in operation)

UPS BYPASS (power supply bypasses UPS)

UPS DISCHARGED BATTERY (critical voltage of UPS battery)

Second and third error signals are always associated with the appearance of the first one. The third error cannot be interpreted for direct current equipment, of course, and cannot be displayed.

Modern UPS units are capable of intelligent communication (e.g. on a serial line, using some standard protocol). With the importance of the error signals it is justified to display the signals with a dedicated


Rev 1.00.01 5/11

wiring, suitable galvanic isolation, and a clear definition of the instrument to electrical interface.

11. To use a blow fuse in the neutral at the 230V AC voltage level, and in the negative line at 24V DC voltage level, is not allowed.

12. Neutral of UPS output must be made common with a grid neutral.

13. Power distribution of the process control system must be made in an instrument power distribution cabinet.

14. An isolating mains breaker shall be used in the instrument power supply cabinet, with which de-energising the power supply cabinet can be made.

15. The instrument power supply cabinet shall be designed so that it can be erected with a ”live line maintenance” procedure.

16. The short circuit protection devices must have a suitable stepping and selectivity.

17. In the instrument power supply cabinet the selection of wire cross sections must be made with sizing to both warming and voltage drop.

18. When designing the equipment it must be taken into consideration that a 10 % installed spare and a 20 % volume spare must be established.

5 Technical requirements These requirements include the minimum specifications for products and services unless indicated otherwise on the relevant data sheets and design documents. Compliance with the personal and asset protection requirements in relation to the products or services, and to the additional requirements necessary for their operation, is the responsibility of the manufacturer, erector, or service provider.

5.1 Power supplies used in process control systems The process control equipment requiring independence from the mains can have both: the direct current or alternating current supply.

1. Direct current power supply is required for field transmitters, field instruments, signal and actuating circuits and the interlock systems of the unit.

2. Alternating current UPS is typically required for field instruments operating from 230V AC power, control room power packs and process control equipment.

3. Non UPS 230V AC supply is required for field devices (e.g. solenoid valves), instrument heating, process control equipment components, lighting in equipment and instrument cabinets, service and ventilation functions, instruments of a higher consumption without interlock functions, or their measurements are not used for calculations statutory accounting data.

4. The process control systems may have their own standalone UPS power supply unit – in which case they do not require an UPS, in any other case their power supply from an uninterrupted voltage must be provided.

5. Direct current 24V DC: see Appendix

5.2 Instrument power supply cabinet or equipment The power supply cabinets shall be located in the control room, and with functions are:

1. To receive the UPS redundant 230V AC supply from the electrical area and to distribute the uninterrupted power to consumers in the control room and on the field, as well as to provide protection to these same consumers.

2. To receive the non uninterrupted 230V AC power from the electrical area, and to distribute the non uninterrupted power to consumers in the control room and on the field, as well as to provide protection to these same consumers.

3. Power distribution of 24V DC: see Appendix.

5.3 Design principles for instrument power supply e quipment The design and erection specifications relating to the process control equipment and the power supply devices are addressed in Book MGS-M-REF-I-7 & MGS-S-REF-I-7

5.4 Installation specifications for power supply eq uipment 1. The equipment of electric power supply shall be located so that nothing prevents the safe work during

erection and inspection, taking into consideration the plant operation and the routine maintenance activities.


6/11 Rev 1.00.01

2. The entry holes of indoor power supply equipment are useful to be made on the bottom or top of the equipment. Suitable sealing of the entry holes must be provided.

3. The entry holes not used on outdoor power supply equipment must be sealed tightly using blinds or plugs.

4. When hooking up power supply a spare of at least 500 mm must be provided on cables, wires etc. to make up for wire breaks unless a longer spare is specified.

5. Support and protective devices of power supply must be provided with a surface protection subject to their material, with special regard given to equipment located outdoors. For carbon steel plate material the surface protection shall be by painting. For plastic, stainless steel and aluminium materials no additional surface protection is required.

6. To fix and assemble power supply equipment galvanised jointing elements must be used.

7. Protecting and support structure of the power supply may be made of plastic, stainless steel plate, carbon steel plate, or aluminium.

8. To fix and assemble the supporting and protecting structures of power supply equipment jointing elements of commercial grade may be used.

9. Material of entries to the power supply equipment for outdoor installations must be stainless steel, for indoor installation plastic, aluminium or bronze can also be used. If entries include soft seals they must comply with the environmental conditions.

PROCESS CONTROL EARTHING SYSTEM

6 Definitions

6.1 Protective earthing A connection, which is able to run the voltages into the ground from parts of the electrical unit, which are de-energised normally but have been energised due to a failure.

6.2 Signal ground (functional earthing) An earthing connection allowing the operation of specific points of the electrical circuits or an equipment. The instrument signal ground means a theoretical equipotential point, which serves as a reference for the system signals.

7 Protective earthing (see Figure 1) The function of the protective earthing system, together with the protective equipment is to keep the contact voltage below values dangerous to humans.

The allowable highest contact voltages in respect of constant or longer time periods are as follows:

1. 50 V AC (120V DC) for fixed equipment, or mobile and portable devices

2. 25V AC (50V DC) for portable devices

3. Values higher than above are allowed if the system can remove dangerous contact voltages at a rate, by which the contact voltage is harmless to humans. The allowed values are given in Table 1.

4. Protective conductors used for earthing of process control systems, process computers and metal parts not energised under operating conditions shall be sized so that in case a ground leakage occurs the contact voltages are kept within the limits defined in Table 1.

5. The cross section of the protective conductors of the above systems can be defined on the basis of Table 2, which can be regarded to be sufficiently safe considering the relatively low currents and voltages of this kind of equipment.

Notes:

• The minimum cross sections Sp given in the table refer to protective conductors, the material of which is the same as that of the phase conductors. In any other case the cross sections must be selected so that they should have a conductivity equal to that indicated.

• In case the device protecting against incidental contact is of the remaining differential current type the cross section Sp of the protective conductors can be 4 mm2 and 2.5 mm2 for unprotected case, and protected case, respectively, irrespective of the cross section S of the phase conductor.

Table 2

7.1 Earthing of control room equipment The typical earthing system and the contact earthing system of unprotected conductor elements for control room equipment are shown in Figure 1.

When developing the earthing system the following specifications must be complied with:

1. For metal parts concurrently accessible and de-energised in normal operation no separate earthing points shall be used.

2. The signal grouding system to be installed separately, and shall be connected to the same earthing bus, to the same earthing system, however the connection is possible at one single point only (see Figure 2).

3. In case the electrical noise level present on the central earthing bus inhibits the proper instrument operation, an additional earthing point must be provided for the signal ground of the electronic equipment.

4. The additional earthing point must be connected to the main earthing point in all cases.

5. In exceptional cases, and if the above recommendations do not result a reduction in noise level to an acceptable value, the facility must be regarded as a special case, and a special solution must be found by involving the authorities concerned.

6. The protective conductors must be sized to the ground short circuit current (for minimum sizes refer to Table 2).

7. In case a ground short circuit occurs the voltage difference between the ends of the protective line – thus between metal parts in metallic contact with it and not energised in normal operation, and the common earthing bus must fall between the allowable values (in Table 1).

8. All electrically conductive elements not energised in normal operation (switching rack, operator station, control panel) must be connected directly to the common earthing bus via a dedicated protective conductor (PE). For large size equipment such as control panels two conductors should be used preferably.

9. The protective conductors shall be made of insulated copper wire, which shall have at least a cross section that can also provide their mechanical protection.

10. For earthing the instrument cabinets a cross section of at least 16 mm2 is recommended.


8/11 Rev 1.00.01

11. The protective conductors must have continuity.

12. Use of socket connections must be avoided. No socket connection shall be allowed for equipment, which under normal operating conditions have a short circuit current in excess of 3.5 mA.

13. The continuity of earthing system connections must be inspected after both the installation and possible modifications at a later date. The inspections must be repeated at regular intervals.

14. The material of the common earthing buses in the control room shall be copper with 3x20 mm minimum cross section.

15. The material of the star earthing bus shall be copper, with 75 mm2 minimum cross section.

7.2 Earthing of the field instruments Concerning field instrument houses and enclosures the international standards set specific requirements (in general equipment with a voltage lower than 50 V).

The specifications concerning the earthing of equipment enclosures are different, subject to the operating voltage of the circuit and to the area classification where they are installed at.

7.2.1 Installation in non Ex area Enclosures of electrical equipment with a voltage higher than 50V AC or DC must be earthed using a “target built” protective conductor (PE), which must be sized to the ground short circuit current (refer to Table 2).

Notes:

• For direct current equipment the standards allow a higher voltage than given, which is practically maximum 120 V.

• The enclosures of electrical equipment with a voltage lower than 50V AC or DC need not to be earthed with a “target built” protective conductor. In that case the equipotential connection between the unprotected conductor elements and the plant structures must be solved via “existing conductors”.

7.2.2 Field installations with Zone 2 Class Regulations relating to not Ex areas are applicable.

7.2.3 Field installations with Zone 0 and Zone 1 In all cases including equipment with a voltage lower than 50V AC or DC the earthing connection must be provided using a target built protective line (PE), which shall be sized to the ground short circuit current (refer to Table 2).

This is not concern to the enclosures of equipment, the energized circuits of which operate at a very low voltage and current such as thermometers, resistance thermometers, and instruments with intrinsically safe circuits unless otherwise specified by the equipment or instrument vendor.

For this type of equipment it is enough to ensure that the equipotential connection of touchable conducting is made with existing conductors if it’s elements not energised in normal operation.

8 Signal functional ground system (see Figure 2) The signal ground or reference ground of process control systems means an ideal equipotential conductor, which serves as a reference point for the system signals.

In practice the earthing systems cannot be considered to be equipotential systems.

1. The signal ground common with the control system (ICS) must be developed in accordance with the specifications by the DCS vendor.

2. Signal ground must be segregated from the protective earthing.

3. The two earthing systems shall be connected electrically at one point, practically on the central earthing bus (Figure 2).

4. Signal ground system must be designed so that no current flows in the conductors, which connect the earthing of specific parts of the equipment to the signal ground common bus.

5. Since in practice it is impossible to prevent current flowing in the reference earthing system the connecting conductors between each system or subsystem and the signal ground common bus must be sized so that at an assumed current the potential difference between the two end points remains below the maximum allowable value, e.g. 4 mV.

6. Generation of earth loops must in all cases be avoided, therefore the conductors must be fitted with insulation.

7. Connection of the cable armouring to the signal ground system is not allowed.


Rev 1.00.01 9/11

8. For intrinsically safe circuits the eathing connections must have a high reliability, and the impedance between the connection point of Zener barriers and the general earthing connection lug must be a value below 1 ohm.

9 Appendix

5.1: Power suppliers used in process control system s ad 5: Direct current 24V DC:

Direct current 24V DC shall be produced by AC/DC power supply transmitters powered from UPS redundant 230V AC.

5.2: Instrument power supply cabinet or equipment ad 3: Power distribution of 24V DC:

230V AC/24V DC power supply transmitters shall be placed in control room in relevant cabinets (e.g. DCS cabinet, PLC cabinet, etc.).
