This screen shows the activation of all voltage elements available in the G650. It can be accessed from the menu: Actual >
Status > Protection > Voltage, and it includes the following signaling LEDs.
The values shown are:
Pickup and operation signals for phase to ground and phase-to-phase undervoltage elements and the three-phase signal
for pickup and operation for the undervoltage element.
Pickup and operation for negative sequence overvoltage element.
Pickup and operation signals for phase-to-phase overvoltage elements and the three-phase signal for pickup and operation
for the overvoltage element.
Pickup and operation for neutral overvoltage element (High).
Pickup and operation for auxiliary undervoltage and overvoltage elements.
Pickup and operation for volts/Hz elements, see note (*).
Pickup and operation for ground overvoltage elements.
