Attention!

PROFITEST⏐PRCD Applications

The test adapter may not be used:

• If external damage is apparent, for example if parts which conduct dangerous touch voltage are freely accessible, if its LEDs are defective (voltage at the PRCD IN would no longer be indicated in this case)

• If the seal or sealing lacquer has been removed as the result of repairs or manipulation carried out by a non-authorized/certified service provider

• With damaged connection and/or measurement cables, e.g. interrupted insulation or kinked cable

• If it no longer functions flawlessly

• After extraordinary stressing due to transport

In such cases, the test adapter must be removed from operation and secured against unintentional use.

2 Applications

Testing of PRCDs with the Test Adapter by Simulating Faults

The following faults can be simulated with regard to mains supply power to the PRCD:

• Wire reversals

• Failure of individual conductors (undervoltage detection)

• Interference voltage on the protective conductor a) by connecting the phase conductor

to the protective conductor (PE-U

switch setting) or

EXT

b) by touching the “on” key of the

single-phase PRCDs with the probe

The evaluation of the PRCD’s reaction to each respective fault is strictly visual:

• PRCD active or inactive (indicator lamp on the PRCD)

• Fault indication by means of LEDs on the test adapter

In any case, comply with the manufacturer’s recommendations concerning tests to be conducted in accordance with DGUV Provision 3.

Testing of PRCDs with the Test Adapter by Simulating Faults and Measuring Protective Conductor and Insulation Resistance, as well as Tripping Current and Time to Trip, using the PROFITEST MXTRA Test Instrument

The following functions are possible after connecting the PROFITEST MXTRA test instrument to the test adapter:

• There are three preset test sequences: Single-phase PRCDs: – PRCD-S: 11 test steps – PRCD-K: 4 test steps 3-phase PRCDs: – PRCD-S: 18 test steps

• The test instrument runs through all test steps semi-automatically: Single-phase PRCDs: 10 test steps 3-phase PRCDs: 17 test steps

• Each test step is evaluated and assessed by the user (go/no-go) for later documentation.

• Measurement of the PRCD’s protective conductor resistance using the test instrument’s R that the protective conductor measure-

function. Please note

ment is a modified RLO measurement with ramp sequence for PRCDs, which is only available with the PROFITEST MXTRA test instrument.

• Measurement of the PRCD’s insulation resistance using the test instrument’s R

function.

ISO

• Tripping test with nominal residual current using the test instrument’s I function.

• Measurement of time to trip using the test instrument’s I

function.

ΔN

• Varistor test for PRCD-K: Measurement via ISO ramp

Measuring Protective Conductor Current

Protective conductor current or bias current may result in premature tripping of PRCDs.

For this reason, the protective conductor is led out of the housing as a loop between surface mount sockets 4 and 6. This makes it possible to measure any protective conductor current with the help of a current clamp transformer.

PROFITEST⏐PRCD Initial Start-Up

3 Initial Start-Up

See the connections overview on page 2 for all connection variants.

3.1 Testing the LEDs

Before performing any measurements, the LEDs should be tested for correct functioning.

Single-Phase Mains Connection

➭ Insert the earthing contact plug into the

earthing contact mains outlet, remove it, rotate it 180° and insert it again.

When connected with correct polarity, the PRCD IN L1 LED must light up, and when rotated 180° the PRCD IN L1 and PRCD IN PE LEDs must light up simultaneously.

3-Phase Mains Connection

➭ Insert the CEE plug into the CEE outlet. The PRCD IN L1, L2 and L3 LEDs must light up. If any of the phase conductors are connected to the neutral conductor, i.e. L1-N,

L2-N or L3-N, N lights up instead Lx. If any of the phase conductors are connected to protective earth, i.e. L1-PE, L2-PE or L3-PE, PE lights up instead of Lx.

3.2 Mains Connection

The test adapter must be connected to the mains for fault simulation, as well as for indication by means of the phase LEDs.

➭ Connect the test adapter to the mains

via the single or 3-phase mains power cable. Refer to the characteristic values on page 14 for nominal mains values.

3.3 Connecting the PRCD

The respective PRCD must be connected to the test adapter for all tests.

Connecting a Single-Phase PRCD

➭ Insert the earthing contact inlet plug from

the PRCD into the earthing contact outlet (4) at the test adapter.

➭ Insert the earthing contact plug (2) from

the test adapter into the outlet coupling socket at the PRCD.

Attention!

PROFITEST⏐PRCD Measurement with the PROFITEST MXTRA

4.1 Measuring Protective Conductor Resistance (Rlo)

As opposed to the usual default setting for low-resistance measurements, the device under test does not have to be disconnected from all sources of voltage in this case. Depending on the PRCD, the rotary selector switches have to be set to the ON and the 1~ ON or 3~ ON positions, in order to be able to activate the PRCD and switch the protective conductor through.

Example of a Single-Phase PRCD

➭ Activate the PRCD. ➭ Perform the measurement as described

in the operating instructions for the

PROFITEST MXTRA

(section 12.2 as of V10).

4.2 Measuring Insulation Resistance (Riso)

The right-hand rotary selector switch must be set to the mains disconnect position: 1~ OFF or 3~ OFF.

➭ In order to perform the insulation mea-

surement (Rins), connect the PROFITEST MXTRA test instrument, via the measuring adapter, to socket 9 for the cable at the mains side and to socket 10 for the cable at the test object’s outlet side.

Example, Single-Phase PRCD OUT Sockets

➭ Before performing protective conductor

measurements, execute an offset measurement to assure that the test adapter’s connector contacts are not included in the measurement results.

➭ Insert the respective test plug into the

appropriate socket at the test adapter to this end: 2 to 4 or 1 to 6.

➭ Start the offset measurement at the

PROFITEST MXTRA

➭ Connect the PRCD as described in sec-

tion 3.3.

➭ Connect the PROFITEST MXTRA test instru-

ment to sockets 9 and 10 via the 2-pole measuring adapter.

4.3 Tripping Test with Nominal Residual Current and Measurement of Time to Trip

If you operate your test adapter at an electrical system with a 30 mA breaker, the mains RCCB may be tripped during the tripping test (tripping current and time to trip) instead of the PRCD. In this case the

In order to prevent an upstream RCD (also non-selevtive RCD) from being tripped and to ensure that the actual tripping current and/or the correct time-to-trip are determined, we recommend the following procedure:

➭ Connect the PROFITEST MXTRA test instru-

ment via the 2-pole measuring adapter with pole (L1) to L1 (PRCD-OUT) and with pole (PE) to N (PRCD-IN). Observe the correct polarity between earthing contact plug and PRCD!

➭ Refer to the operating instructions for the

PROFITEST MXTRA regarding performance of the measurement Type K PRCD, section 7.3.2 Type S PRCD, section 7.3.3

MAINS L1

LED goes out.

4.4 Varistor Test (PRCD-K)

During this measurement, the voltage is ascertained at which the varistor becomes conductive, thus checking the varistor for correct functioning as well. Measurement can be performed by means of an ISO ramp, or with a fixed test voltage of 50 V.

As a prerequisite for this measurement, the device under test must be switched on.

➭ Connect the PROFITEST MXTRA test instru-

ment to the PE IN and PE OUT sockets via the 2-pole measuring adapter.

➭ Perform the measurement as described

in the operating instructions for the PROF- ITEST MXTRA (section 11).

➭

The evaluation of the measured varistor resistance depends on the manufacturer’s specifications (PRCD-K from Kopp: e.g. 12 to 22 V according to Kopp).

Note on Kopp Test Specification: PRCD-K (Varistor in Protective Earth Circuit)

Test Sequence by Kopp:

1.) Connect operating voltage (e. g. 230 V/ 50 Hz) and 24 V AC voltage source.

2.) Select resistance (R) depending on the residual current of the PRCD-K:

For PRCD-K with In = 30 mA → R = 220 Ω/1 W.

For PRCD-K with In = 10 mA → R = 620 Ω/0.5 W.

3.) Switch on PRCD-K by pressing the ON button.

4.) Press key <T> circuit is functioning properly.

→ device must trip → PE

The shutdown test of the PRCD-K stipulated by KOPP at this point is performed in connection with the testing of the RCD protection device with a continuously rising residual current until the device is tripped.
