Figure 11:
Overvoltage protection
Three overvoltage protection stages (PHxPTOV) protect against abnormal phase
voltage conditions in the power system. The operation of voltage functions is
connected to alarm LED 1.
Depending on the selected operation mode, the active setting group can be changed
either with a parameter or via binary input.
All operate signals are connected to the Master Trip and also to the alarm LEDs.
LED 1 indicates operation of overvoltage and LED 2 operation of undervoltage
protection functions. LED 3 indicates operation of residual overvoltage and LED 4
voltage unbalance protection. LED 5 indicates operation of frequency protection.
