PAP208

The PAP series 3-phase Monitor Relay continuously monitors all voltages of a 3-phase system. It is used to protect motors and equipment from expensive damage due to phase loss, phase reversal and undervoltage. This device detects single phasing and unbalanced voltages regardless of regenerative voltages. It incorporates a microprocessor-based design capable of advanced signal processing including True RMS voltage measurement. Innovative analogue-to-digital sensing circuitry allows for true full-wave monitoring of all 3-phase, delivering the highest level of protection possible. True RMS voltage measurement ensures accurate sensing in most generator and other applications with non-sinusoidal wave forms, eliminating nuisance tripping. Full wave monitoring provides a more accurate method to measure the voltages, regardless of load type or wave shape, resulting in improved protection across more applications. This relay will continue to function even with a lost phase.
