release or trip from a function. Also check that the wanted recordings of analog (real and
calculated) and binary signals are achieved.
During testing, observe that the right testing method, that corresponds to the actual
parameters set in the activated parameter setting group, is used.
Set and configure the function(s) before testing. Most functions are highly flexible and permit
a choice of functional and tripping modes. The various modes are checked at the factory as
part of the design verification. In certain cases, only modes with a high probability of coming
into operation need to be checked when commissioned to verify the configuration and
settings.

Activating the test mode

Put the IED into the test mode before testing. The test mode blocks all protection functions
and some of the control functions in the IED, and the individual functions to be tested can be
unblocked to prevent unwanted operation caused by other functions. In this way, it is possible
to test slower back-up measuring functions without the interference from faster measuring
functions. The test switch should then be connected to the IED.Test mode is indicated when
the yellow StartLED flashes.
It is important that the IED function to be tested is put into test mode, even if the MU is
sending data marked as "test". The IED will interpret these data as valid if it is not in test
mode.

Preparing the connection to the test equipment

The IED can be equipped with a test switch of type RTXP8, RTXP18 or RTXP24. The test switch
and its associated test plug handle (RTXH8, RTXH18 or RTXH24) are a part of the COMBITEST
system, which provides secure and convenient testing of the IED.
When using the COMBITEST, preparations for testing are automatically carried out in the
proper sequence, that is, for example, blocking of tripping circuits, short circuiting of CTs,
opening of voltage circuits, making IED terminals available for secondary injection. Terminals 1
and 8, 1 and 18 as well as 1 and 12 of the test switches RTXP8, RTXP18 and RTXP24 respectively
are not disconnected as they supply DC power to the protection IED.
The RTXH test-plug handle leads may be connected to any type of test equipment or
instrument. When a number of protection IEDs of the same type are tested, the test-plug

Parameters can be entered into different setting groups. Make sure to test
functions for the same parameter setting group. If needed, repeat the tests for
all different setting groups used. The difference between testing the first
parameter setting group and the remaining is that there is no need for testing
the connections.
