Series Features
PAP Series PHASE LOSS, PHASE REVERSAL & UNDERVOLTAGE
Series Description:The PAP Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal and undervoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages.
Utilizing an advanced microprocessor-based design allows true RMS voltage measurement with full wave monitoring. This provides a more accurate method to measure the voltages, regardless of load type or wave shape, and results in improved protection across more applications.
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.
Unlike similar three-phase monitor relays, the PAP Series will continue to function even with a lost phase. They are the only line-powered units in their class to retain fault indication and continuous monitoring of all voltages during a phase loss, increasing the ease of troubleshooting and the level of protection.
The PAP Series have an adjustable undervoltage trip point of 75-95% of the line- line voltage setting. They utilize an industry-standard 8 pin octal socket.
