Protective Conductor Current Measurement (IPE) at Mode 2 Charging Cable

7.5 Guided Test Sequences

(not possible with PROFITEST MXTRA

and PROFITEST MTECH+)

Test sequences are available for the test

instruments. The test instrument runs

through all test steps semi-automatically.

Each test step is evaluated and assessed by

the user (go/no-go) for later documentation.

It depends on the respective test instrument

whether or not and which test sequences

are available.

The test sequences are provided free of

charge for download from the myGMC por-

tal, however, it is the responsibility of the

user to import them into the test instrument.

➭ Create a myGMC account and register

your test instrument (both free of

charge):

https://www.gossenmetrawatt.de/

services/mygmc/

➭ Download the test sequence(s).

➭ Transfer the test sequence(s) to your test

instrument. Complete information can be

found in the product documentation for

the respective test instrument.

➭ Perform the test sequence with the test

instrument and the test adapter.

Detailed information on the test se-

quences can be found in the product

documentation of the respective test in-

strument.

8 Protective Conductor Current

Measurement (I

) at Mode 2

Charging Cable

Protective conductor current or bias current

may result in premature tripping of RCDs

used in ICCBs.

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 con-

ductor current with the help of a current

clamp transformer.

You therefore require an additional current

clamp transformer (e.g. METRACLIP 61).

➭ Connect the test object as described in

chapter 5.3.

➭ Switch mains voltage on by turning the

top rotary selector switch (S1) to the Sta-

tus C position (system state: vehicle

ready for charging).

➭ Turn the bottom rotary selector switch

(S2) to the first ON position in the orange

area for single-phase interruption.

➭ Close the jaws of the current clamp

transformer around the external protec-

tive conductor loop I

➭ Read the measured value for protective

conductor current at the current clamp

transformer.

Protective conductor current should not

exceed 3.5 mA.
