Commissioning: Undervoltage Protection [27M]
This test can be carried out similar to the test for overvoltage protection 59M
(by using the related undervoltage values).
Please consider the following deviations:
For testing the threshold values, the test voltage has to be decreased until the relay is activated.
For detection of the dropout ratio, the measuring quantity has to be increased to achieve more than the set drop
out ratio of the trip value. Above the set drop out ratio of the trip value, the relay is to dropout at the earliest
moment.
