7.15. Overvoltage (59)
Two overvoltage elements are provided for trip, alarm and control when the voltage rises above a
specified voltage for a specified time.
The overvoltage element can be ON or OFF in the Primary, Alternate settings . The overvoltage
element can be selected the type of operation required with any one phase, any two phase and
three phase.
When the circuit breaker is closed by a local/remote controls, the overvoltage element is disabled
from detecting for the cold load pickup during periods. To increase security, all overvoltage
elements add two power frequency cycle of intentional delay to prevent incorrect operation.
Overvoltage 1 Setup
The overvoltage 1 should be enabled to the following settings.
PRIMARY SETTING / PROTECTION / VOLTAGE / OVER VOLTAGE 1 / Function
Range
OFF, TRIP, TR&AR
Default
OFF
Step
~
If function = OFF,
the feature is not operational.
If function = Trip,
the feature is operational.
If function = Trip & AR,
the feature is operational. When the feature
asserts a TRIP & AR condition, it trips and alarms.
PRIMARY SETTING / PROTECTION / VOLTAGE / OVER VOLTAGE 1 / Relays(0-8)
Range
OFF, 0 ~ 8
Default
OFF
Step
1
Selects the relays required to operate when the feature generates a Trip.
PRIMARY SETTING / PROTECTION / VOLTAGE / OVER VOLTAGE 1 / Pickup(xVT)
Range
0.00 ~ 1.25 xVT
Default
1.20
Step
0.01
Enter the pickup value as a fraction of the secondary nominal voltage.
For example, if the secondary nominal voltage is 100 V, and an alarm is
required whenever the voltage exceeds 120 V, enter 120 / 100 = 1.20
for the pickup.
