摘要

The relay system (10) obtains voltage and current values from a power line anduses a first sampling element to sample the voltage and current values atselected intervals of time. The resulting sampled signals are used for powersystem-wide protection, control, monitoring and metering. The sampled signalsare then resampled at a rate which is a selected multiple of the power systemfrequency. The results of the resampling are used by processing circuitry forprotection functions including fault determinations.
