Voltage Unbalance

Field

Description

Applications

The single-phase loading causes a voltage unbalance. When the maximum deviation from average voltage is greater than a user-specific value of the average voltage, the sensor indicates a failure.

  • The voltage unbalance is only for 3P 3-wire.

  • The voltage unbalance is only for TransferPacT Active Automatic.

Default value

  • The voltage unbalance feature can be enabled or disabled. By default, this feature is disabled.

  • When there is a voltage unbalance after enabling the sensor, it will raise an alarm and transfer is initiated.

  • The default value for voltage unbalance is disabled

Range

The adjustment range for voltage unbalance is between 2%–30%.
