Testing the energizing check
During test of the energizing check function for a single bay arrangement, these voltage inputs
are used:
12.3.1
At test of the energizing check function for a 1 1/2 CB diameter the following alternative voltage
inputs can be used for the three energizing check functions. The voltage is selected by activation
of different inputs in the voltage selection logic:
12.3.2
Testing the dead line live bus (DLLB)
The test should verify that the energizing function operates for a low voltage on the U-Line and
for a high voltage on the U-bus. This corresponds to an energizing of a dead line to a live bus.
The settings in
table 12
can be used during the test if the final setting is not determined.
