12.7.5 OVERVOLTAGE
To protect voltage sensitive loads and circuits against sustained overvoltage conditions, the overvoltage 1 and
2 protection features can be used to either cause a trip or generate an alarm when the voltage exceeds a spec-
ified voltage setting for a specified time delay.
The following setpoints are repeated for both Overvoltage 1 and Overvoltage 2.

The Overvoltage 1 setpoints path is:
\ SETPOINTS \ S5 PROTECTION \ VOLTAGE \ OVERVOLTAGE 1
OVERVOLTAGE 1
FUNCTION: Disabled
Range: Disabled, Trip, Alarm, Latched Alarm, Control
Select the required function.
OVERVOLTAGE 1
RELAYS (3-7): -----
Range: Any Combination of the 3-7 AUXILIARY Relays
Select the output relays required.
OVERVOLTAGE 1
PICKUP: 1.25 x VT
Range: 0.00 to 1.25 in steps of 0.01 x VT
Selects the pickup as a fraction of the nominal bus VT Secondary Voltage. For
example, if the nominal VT secondary voltage is 120 V, and an alarm is
required whenever the voltage exceeds 130 V, enter 130 / 120 =
1.08 for the
pickup.
OVERVOLTAGE 1
DELAY: 2.0 s
Range: 0.0 to 6000.0 in steps of 0.1 s
Selects the delay required.
PHASES REQUIRED FOR
OPERATION: All Three
Range: Any One, Any Two, All Three
Select the type of operation required.
