Rotoguard

Rotor winding protection for synchronous machines

Rotoguard

Lack of maintenance, operational knowledge or monitoring systems can cause catastrophic failures in large machines and with this in mind, experts at Quartzelec have designed a state of the art system which provides protection, operational information and ongoing monitoring, allowing detection of early signs of deterioration.

ATEX certified, Quartzelec’s Rotoguard is a telemetry system designed for monitoring and protecting the rotor winding of synchronous machines. It enables a true measure of fault resistance from 50kΩ to 500Ω to be made, without any influence from the DC field component of excitation. By giving an early warning of deterioration of the rotor insulation and providing a continuous readout of the rotor earth leakage resistance and winding temperature, the system forms the basis for an ideal protection scheme for synchronous machine rotors.
