A brief description of the various tests will be given below.
14.3.1 Automatic test of the release PR122/P
• In the absence of the PR120/V measuring module:
with the automatic test, a sequence of 7 different tests will be performed at the currents and phases
indicated in the following table:
• In the presence of the PR120/V measuring module:
with the automatic test, a sequence of 13 different tests will be performed at the currents, voltages,
phase shift and phases indicated in the following table:
