EDR-5000
IM02602007E
Commissioning: 81U
Δ
R – Underfrequency and DF/DT
Object to be tested:
All frequency protection stages that are projected as f< and Df/Dt.
Necessary means:
Three-phase voltage source and
Frequency generator that can generate and measure a defined frequency change.
Procedure:
Testing the threshold values
Feed nominal voltage and nominal frequency to the device;
Decrease the frequency below the f< threshold; and
Apply a defined frequency change (step change) that is above the setting value (example: apply a frequency
change of 1 Hz during the set time interval DT if the setting value DF is 0.8 Hz ). The relay has to trip
immediately.
Successful test result:
Permissible deviations/tolerances and dropout ratios can be taken from the Technical Data.
Commissioning: 81O
Δ
R – Overfrequency and DF/DT
Object to be tested:
All frequency protection stages that are projected as f> and Df/Dt.
Necessary means:
Three-phase voltage source and
Frequency generator that can generate and measure a defined frequency change.
Procedure:
Testing the threshold values
Feed nominal voltage and nominal frequency to the device;
Increase the frequency above the f> threshold; and
Apply a defined frequency change (step change) that is above the setting value (example: apply a frequency
change of 1 Hz during the set time interval DT if the setting value DF is 0.8 Hz ). The relay has to trip
immediately.
Successful test result:
Permissible deviations/tolerances and dropout ratios can be taken from the Technical Data.
