P1/2-5

The "protection" and "continuity" of the

electrical power supply are two terms

that must not be separated if we wish to

guarantee the safety of users and elec-

trical installations.

The recent addition of receivers or loads

that generate distortion in the electricity

grid (speed variators, electronic start-

up units, computer equipment, lighting

with electronic ballasts, etc.) has made

necessary the use of protection systems

that can distinguish between defects in

the installation and the electrical altera-

tions that cause the unwanted tripping

of protection systems.

The new range of earth leakage pro-

tection products offers state-of-the-art

performance to guarantee the continuity

and safety requirements:


} Monitoring in true root mean square.

} High frequency ltering

} Inverse curve delay (instantaneous

and selective)

} Adjustment of the nominal sensitivity

trigger

} Display of the fault current (monitor-

ing of protection systems)

Monitoring the status of protections al-

lows us to do the following in the electri-

cal installation:

} Analyse the insulation conditions.

} Preventive and corrective mainte-

nance.

} Reduce production downtime. De-crease maintenance costs. Quick loca-

tion of faults.

When the earth leakage protection sys-

tem detects a fault current, it acts on the

electrical installation being protected,

opening the circuit while interrupting

the supply of electrical energy, thus pre-

venting the danger of electrocution for

persons when the fault current reaches

dangerous values, either as a result of

direct or indirect contact, including any

potential damage caused to goods and

materials.

An earth leakage protection system is

composed of three clearly different parts:

} Detecting element or sensor

} Relay} Circuit breaker

Detecting element or sensor: Cur-

rent transformer that detects the earth

leakage current of active conductors in

an installation, sending a proportional

signal to the relay. It can have a toroidal

or rectangular geometry, depending on

the arrangement of plates or the wiring

of the installation location.

The correct operation of the sensor re-

quires the path of capacitors to be as

perfectly aligned as possible.

Relay: Smart protection element. It

measures and treats the signal received

Denition

Nowadays, "sympathy" or unwanted

triggers are quite common in modern in-

stallations. In these cases, one or more

earth leakage switches are triggered si-multaneously, protecting an installation

from the leakage currents sent to earth

as a result of capacitive effects caused

by the installation.

Said capacitive effects can explained by

two reasons:

} The installation's cables cause earth-

ing condensation effects. The longer the

cable, the greater the capacity effect

} The capacitors of EMI lters in the

equipment with electronic power regula-

tion

Immunised earth leakage protection

by the sensor and either sends the trigger

signal to the associated circuit breaker

or not, depending on the sensitivity and

delay time values programmed.

Circuit breaker: This element acts as

the current interrupting element. It can

be a circuit breaker (with trigger coil), a

contact, etc.

These three elements can be found in

CIRCUTOR's products with different

congurations:

} All elements separately

} Relay with internal transformer

The different loads or consumption of an

installation can be classied in two main

groups, depending on the type of insula-

tion from earth:

Loads with no earthed capacitors

The insulation existing between the unit

and the earthing elements can be rep-

resented with a pure Ohmic resistance.

If the resistance is not high enough, no

current will pass through the earthing

elements. The leakage current is zero

(current passing to earth under normal

conditions).

In case there is an insulation fault, cur-

rent will pass through earthing elements,

the so-called fault earthed current, Id.

8/11/2019 Ca_P1_03

5/42


P1/2-7

In this case, we must simply adjust the

sensitivity and delay time to guarantee

the adequate protection.

Loads with earthed capacitors

The current passes through the earthing

elements as a result of the unit's opera-

tions through its capacitors. In addition,

the length of cables in an electrical in-

stallation can lead to capacitive earthing

faults, which would lead to this situation.

The current can be injected with two

methods:

Permanent Leakages.

The unit injects current in the earthingelements permanently. This type of be-

haviour is closely tied to the use of EMI

lters, which are installed in most ma-

chines or loads with electronic power

regulation, in order to comply with the

electromagnetic compatibility directives.

This type of lter prevents the high fre-

quency distortion generated by the re-

ceiver from being returned to the grid.

However, it is transferred through the

earthing capacitors. It also transfers in-

directly the fundamental frequency and

its corresponding harmonics, so that the

leakage is usually a set of overlapping

high and low frequency signals. There-

fore, it increases the risk of an earth

leakage trip with no real earth leakage

current.

Transient Leakages.

It has the same capacitive effects of ca-

bles and the lters mentioned above for

transient overvoltages caused by grid

switching effects, the connection-dis-

connection of circuits or effects that are

simply caused by atmospheric agents.

In case of loads with earthed capaci-

tors, the basic problem for the protec-

tion of the system is to distinguish whichearthed current is part of the unit's op-

eration and which is part of an insulation

defect. Electromechanical earth leak-

age relays do not usually solve these

situations.

The immunised earth leakage protection offered by CIRCUTORhas evolved in relation

to ve factors, in order to satisfy the needs of our customers, catering for the current

demand as regards the safety and continuity of the supply of electricity:

} MEASUREMENT IN TRUE ROOT MEAN SQUARE (TRMS) AND CLASS A

} IMMUNE TO TRANSIENT LEAKAGES

} HIGH FREQUENCY FILTERING

} ADJUSTMENT OF THE TRIGGER OF In

} INVERSE CURVE

1/2-8

Measurement in TRMS and Class A

The voltage and current wave shapes

have stopped being complete sine

waves since the loads distributed in the

installations are not linear. The continu-

ous and harmonic components can dis-

tort the wave shapes, whereby it will be

necessary to take more accurate meas-

urements.

The current range of electronic earth

leakage switches measures the root-

mean-square-value (TRMS) of leakage

currents by sampling it.

The wave shapes in installations with

linear resistive loads are pure sine-

waves. However, the gure shows howthe mean value will not work to measure

the root-mean-square-value with ac-

curacy when it stops being a complete

sine-wave.

In accordance with these problems,

the IEC 61008-1 Earth Leakage Switch

Standard determines the types of op-

eration, depending on the type of wave.

Two types are dened, Class AC and

Class A.

CLASS AC

The earth leakage devices used in do-

mestic installations or that protect loads

that do not cause distortions can be of

the AC Type. These devices are marked

with a symbol, in compli-

ance with the IEC 61008-1

Standard.

CLASS A

In the presence of non-linear receivers,

Type A earth leakage protection sys-

tems must be used, which means that

rectied currents can be measured with

a continuous component of up to 6 mA,

including non-distorted currents (AC

type), marked by the cor-

responding IEC 61008-1

Standard.

The IEC61008-1Standard denes two

types of ray-type curves to check thecorrect operation of an earth leakage

device: an overload and an overvolt-

age wave. The overload wave shows

the effects caused in the measurement

of the earth leakage device and the ov-

ervoltage wave shows the effects in the

power supply.

Immunity against transient leakages

The behaviour of earth leakage pro-

tection units in the case of transientoverloads and overvoltages is vital to

maintain the continuity in the supply of

electricity. Therefore, the immunised

earth leakage protection relays manu-

factured by CIRCUTOR can support

very high peaks.

High-frequency current

Adjustments of In

The IEC 479-1/ UNE 20-572-92Stand-

ard describes the effects of currents

passing through the human body for

a frequency of 50 Hz. As you can see,

the effect depends on the root-mean-

square-value of the current passing

through the body and the time it takes

to pass through. In accordance with the

effects, we can establish zones 1 (zone

with no perception) and 2 (perception

zone) as safe work zones. Therefore, in

terms of the protection of persons, earth

leakage protection systems must act on

those zones.

When the frequency increases, the

curves are displaced to the right of the

The following graphs show that with an

identical evolution of the fault earthed

current in the same installation, the be-

haviour of the earth leakage switch is

different, even when the sensitivity level

of Inis the same in both cases.

This adjustment of In

allows us to con-

centrate more loads that incorporate

earthed capacitors within the same line

being protected. For example, in a com-

puter installation: Each unit diverts a

current, Ileakage

, of 2 mA through the EMI

lter capacitors included. At a sensitiv-

ity of (In

) 30 mA, you can install 7 com-

puters with the electromechanical earth

leakage switches. However, if you use

CIRCUTOR's electronic switches youcan install a total of 12.

The IEC 61008-1 Standard species

that earth leakage switches must be

triggered when the fault earthed current

is between 50% and 100% of the sen-

sitivity value (In

) selected. This means

that the values that exceed 50% canset off the earth leakage switch trig-

ger. This type of case is common with

electromechanical switches. In the case

of electrical energy installations, these

have evolved in such a way that the ad-

justment of protection can cause great

problems, since it is too low. The elec-

tronic earth leakage protection systems

offered by CIRCUTOR determine the

trigger near 100 % of In

.

Therefore, we have a lower risk of trig-gers and less interruptions in the instal-

lation's supply than when the fault cur-

rent is lower than In

.

previous graph, which indicates that the

current is less dangerous.See the table

attached, in accordance with IEC 479-2/

UNE 20-572-93, where a fault current

of, for example, 45 mA at 500 Hz has

the same effect as a fault current of 30

mA at 50 Hz. In the case of receivers

with EMI lters, we can consider that

these inject a high-frequency earthed

current (>2 kHz) and a low frequency

current. The use of type A earth leakage

protection systems is specied in these

cases.

Inverse curve

Monitoring protection elements

Remote control and reset

The IEC 61008-1Standard allows us to

incorporate a circuit opening delay for

the circuit being protected, which will

depend on the leakage current level.

Therefore, the greater the fault current,

the lower the delay.

Two types of curves are specied, as

shown on the following table of values:

} Instantaneous

} Selective

The application of these curves to our

earth leakage systems can be used to

increase the continuity in the installa-

tion's power supply and avoid unwantedtrips.

The leakage current value must be

available at all times in many applica-

tions. This information is quite useful for

the installation's preventive and correc-

tive maintenance tasks, since we can

act before triggers are set off.

For example, if the insulation degree of

a machine is reduced, the earth leakage

current increases, and since we have

the said information, we can implement

the appropriate corrective actions to

avoid the trigger from being set off.

The idea is to integrate the earth leaka-

ge currents in the installation's energy

control system, thus controlling an addi-

tional quantity.

Depending on the type of product, the

information can be presented as fo-

llows:

} In the earth leakage relay, through

the display.

} Through the RS-485 communica-

tions system.

} With an auxiliary measurement unit.

In addition, records and logs of the in-

sulation behaviour of the installation can

be taken.

In the case of earth leakage protection

systems in installations that require a

continuous supply of energy, with no

maintenance staff present, the remotecontrol and reset (or self-reclosing)

functions are very useful.

Remote control functions can be carried

out through communications systems

(RS-485, Ethernet, etc.), using the Power-

Studio Scada software. This function cancontrol the status of protection systems

and perform a set of actions through a

computer and communications systems.

Earth leakage protection systems with self-reclosing

Given the current efcient personal and

material protection requirements and

obligations, and the complexity of some

installations that require the continuous

supply of electrical energy with the use

of overload and earth leakage protection

systems, CIRCUTOR has developed a

wide range of units that make safety and

service continuity compatible.

Self-reclosing systems are an ideal solu-

tion for installations that need a constant

supply of electrical energy, without the

need for the usual maintenance staff:

} Rural installations} Refrigeration chambers

} Public lighting

} Mobile telephony repeaters

} Trafc lights

} Lighting of tunnels

} ATMs

} Cable television

} Etc.

The type of protection element installed,

those that can be reclosed and under

which reclosing conditions must be known

by all self-reclosing systems.

Self-reclosing systems act in accord-

ance with the following:

} Earth leakage current (earth leakage)

} Earth leakage current (earth leakage) +

overload and short-circuit (circuit breaker).

Elements that form an self-reclosing system

Earth leakage transformer

The earth leakage transformer detects

the earth leakage. It can be built-in on a

relay or as an external element.

Self-reclosing relay

Self-reclosing relays add a series of

performance features (self-reclosing,

thermal or overload protection) to the

proven reliability and security of non-re-

closing earth leakage protection relays.

It performs the following functions:

} Detection of anomalies (earth leak-

age or overload) through the signal gen-

erated by the transducer.

} They analyse the anomaly to see if it

must generate an alarm, depending on

the parameters programmed.

}They also act on power elements,

which perform the grid load connection-

disconnection tasks.

Circuit breaker

The circuit breaker always interrupts the

ow of power, which supports the power

in the line protected and is an external

element of the relay.

The circuit breakers that can be asso-

ciated to self-reclosing relays are as

follows:

} Motorized circuit breaker (MT)

} Contact circuit breaker with remotecontrol (MCB), with a dual circuit break-

er and contact function (the function of

the contact is bistable).

Features of the circuit breaker:

} Nominal current (in contacts)

} Nominal current and thermal protec-

tion curve (in circuit breakers)

} Features of the control inputs of the

operational element

}Circuit-breaking power} Auxiliary NO or NC signalling of the

circuit breaker's status

Parameters related to self-reclosing relays

Relay status indicator

The indications are associated to the

type of protection, distinguishing be-

tween instantaneous triggers and inter-

lockings. The indications are sent by the

relay (LED) and, optionally, by auxiliary

contacts.

Another type of visualisation, depending

on the relay, is the instantaneous trigger

value and the number of total reclosures.

Nominal trigger point of protec-

tions

Standard values:

} Earth leakage protection 30 mA - 3 A

} Overload protection 6 A - 63 A

Timer (delay)

Minimum time that the earth leakage

must last before setting off a relay trig-

ger.

Standard values: 20 ms - 1s.

Relay power supply and tolerance

Self-reclosing relays need a permanent

form of auxiliary power supply in order to

manage the self-reclosing operations.

} Standardised value: 230 Vac 15 %

} Optional: 48, 110 or 400 Vac

Reclosing meter reset time.

To avoid the accumulation of triggers thatdo not correspond to the same anomaly,

a reset time is dened for the reclos-

ing meters, provided that the maximum

number of reclosures is not exceeded.

Example: The WRU-25 RArelay has a

maximum number of reclosures available

before being pushed to its interlocking.

In installations with a transient earth leak-

age fault that lasts 50 seconds, the relay

is triggered 4 times and reclosed 3 times(8 s + 16 s + 30 s). During the timing of

the third self-reclosing, the fault disap-

pears, so that the relay will remain in the

ON position. This is when the reset timer

of the reclosing meter will be set off.

The RESET option starts the relay, reset-

ting the reclosing meters.

Local (with the keys) and remote

test and reset

Self-reclosing earth leakage relays offer

the same performance as non-reclosing

relays. It enables the verication of the

correct operation of the relay with local

TEST and RESET functions, using the

keys on the relay, including remote func-

tions with specic inputs.

The RESET option resets the relay and

the reclosing meters.

Number of reclosures, distin-

guished by type and number of

self-reclosing

Each relay enables a maximum number

of reclosures before setting off the in-

terlocking. The meter will be reset au-

tomatically if the maximum number of

reclosures is not exceeded within a pre-

established period of time (reset time of

reclosing meters).

This number will be different, in accord-

ance with the type of self-reclosing.

Application

The RGU-10 relays associated to the trans-

formers of the WG series allow an smart

earth leakage protection. Their design fea-

tures guarantee maximum security and con-

tinuity of the electrical service, avoiding un-

wanted tripping.

Showing the value of the leak instantane-

ously on the display with the pre-alarm in-

dications provides the information about the

state of lines being protected, thus allowing

the implementation of an adequate preven-

tive maintenance approach.

In addition, version RGU-10 Cwith RS-485

communications is used with the Power Stu-

dio software, which allows the centralisedsupervision of the system in real time, with a

record log that can be analysed later on.
