13.3.1 Automatic test of the release PR121/P
With the automatic test, a sequence of 7 different tests will be performed at the currents and
phases indicated in the following table.
The trip times of the release in the various tests will depend on the settings of the protections; on
the display the PR010/T unit will show the trip time and the result of the test (OK;FAILED).
At the end of the test it is asked whether to record a test report which may later be downloaded on
a PC.
13.3.2 Manual Test
The manual test allows testing of the release trip time with the desired load condition, in
particular it offers the possibility of selecting the current value in a range between 0.00 and 16.00
In and of selecting the phases involved in the test (L1, L2, L3, Ne, Gext).
The release trip time will depend on the settings of the protections; on the display the PR010/T
unit will show the trip time and the result of the test (OK, FAILED).
At the end of the test it is asked whether to record a test report which may later be downloaded on
a PC.
