PCS-985RE Rotor Earth-Fault Relay
The PCS-985RE is mainly designed for rotor earth fault by external voltage injection. Because of adopting self-adaptive active switching technology, The PCS-985RE can still supervise rotor insulation even if no excitation voltage is applied. It has high sensitivity and the same sensitivity to any one-point earth fault within the rotor winding. The automatic and manual control function to electric brush ensure rotor earth fault protection can be applied to the brushless exciter units.
