ABSTRACT:
Spurious subsynchronous and supersynchronous electrical signals in an electrical power system are detected rapidly and reliably by generating an electrical signal which is proportional to the power signal and rectifying the generated signal. The rectified signal includes a dc component and a component having a frequency equal to the difference of the contact power frequency and the spurious signal frequency. The component is readily identified by a tuned filter and detector whereby remedial action can be taken to eliminate the spurious signal.
