BV1 - Phase Sequence Relay
BV1 - Phase sequence relay Application Supervision of phase loss, phase sequence and undervoltage in three-phase systems.
Function Relay BV1 measures amplitude and angle of three phase voltages.
The angle of the phasors determine the phase sequence.
Unbalance and phase loss are detected by the measurement of amplitude and angle.
www.DataSheet4U.com The undervoltage trip setting is 70 % of Un fixed.
The underfrequency element trips if the frequency falls below 45 Hz.
Technical data rated voltag
