Alstom VDG14AF9001ACH displacement relay product features
Belonging to the VDG14 series voltage neutral point displacement relay, it is used to detect voltage offset in power systems.
Adopting a heavy damping induction disk structure with adjustable inverse time voltage characteristics.
The coil circuit is tuned to the power frequency by connecting reactors and capacitors in series, ensuring accurate measurement.
Powered by an autotransformer with taps, the voltage setting value can be easily adjusted through a plug-in bridge.
When the voltage exceeds the set value, the reactor saturates and becomes detuned, possessing a high continuous rated voltage capability.
Adopting a unique coil winding method to ensure consistent time/voltage characteristics on each voltage tap.
Equipped with a tuned short-circuit winding, it generates maximum torque at the power frequency and has low sensitivity to third harmonic voltage.
The action time can be adjusted by rotating the rolling disc on the scale base.
For single pole relays, only single pole versions are available.
High coercivity permanent magnets are used for disk damping, and the detachable design is easy to maintain.
