Supervision
Commissioning: Loss of Potential
Object to be tested:
Test of the module
LOP.
Necessary means:
Three-phase current source
Three-phase voltage source.
Procedure
Test part 1:
Examine if the output signal »LOP B
LO
« becomes true if:
•
Any of the three-phase voltages becomes less 0.01*Vn Volt
•
The residual voltage is less than 0.01*Vn Volt or the %V2/V1 ratio is greater 40%
•
All three-phase currents are less than the load current / overcurrent detection (I<) threshold.
•
The residual current is less than 0.1 Ipu (rated current)
•
No pickup of an OC element which should blocks VT Supervision
•
The breaker is closed (option, if a breaker is assigned).
•
The offline detection has not detected a dead busbar (No current, no voltage measured).
