Title: New static relay for transmission line protection

A new static ac voltage relay is described which meets the requirements of critical applications. This Static Line Voltage (SLV) relay consists of three independently adjustable detectors, each of which can be operated in the undervoltage or overvoltage mode. Each detector has a dropout to pickup ratio of 99 percent, and a high degree of immunity to harmonics (less than 3 percent variation in operating point with a voltage waveform containing 50 percent third harmonic). The outputs of the individual detectors are user programmable in the type SLV relay to provide AND, OR, or other logical combinations of output contact wiring to the external control circuits. 2 refs.
