My point is the 240 is not working correctly as a CURRENT monitor in low side placement. The 240 instead acts like a VOLTAGE monitor producing a single ended NON-bipolar output that is neither linear or bidirectional representation of total inductive Phase current. The only reason 240...
The PMP Series Phase Monitor Relays utilize a microprocessor-based design to provide protection against phase loss, phase reversal, phase unbalance,undervoltage and overvoltage. The PMPU is a universal voltage product that works on any three-phase system voltage from 208-480V (a separate 120V ...
