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

摘要： The residual phase currents for each selected winding of a transformer are first determined and then summed to provide a value designated I.sub.X. The neutral current for the transformer is also determined, with the neutral current being designated I.sub.Y. A directional element calculates a torque value T according to the following formula: T=R.sub.e (I.sub.X .multidot.I.sub.Y *). This torque value will be negative for an external (reverse) fault, and positive for an internal (forward) fault. The quantity of the torque is compared against threshold values before a forward or reverse fault for the transformer is declared.
