Abstract
Systems and methods may be used to determine whether waveforms of at least two transmission lines are synchronous. More particularly, this disclosure relates to sensing operations that use signals received by a local relay and a remote relay to determine whether two waveforms on opposing ends (e.g., supply side and load side, local side and remote side) of a transmission line are synchronous with one another. A system may determine whether a first waveform is synchronous with a second waveform based at least in part on a comparison of delay between a representation of the first waveform and a representation of the second waveform. The system may actuate a device (e.g., close a circuit breaker) in response to determining the first waveform is synchronous with the second waveform.
