Three-Phase ProtectorPhase Monitoring Relay
Shiva Amvaj Microprocessor Phase Monitor is designed and built in a small size with high accuracy and efficiency and a sealable panel (to prevent access and changes to the set parameters by unauthorized people).
With this device, disturbances caused by phase loss, phase sequence reversal, phase imbalance, and voltage rise or drop can be controlled in all industrial, commercial, and residential sites.
(Note that model MRJN-2P is specific to elevators and cannot detect phase sequence reversal. )
