Three-Phase ProtectorPhase & Load Monitoring Relay


The phase-load monitor is designed and built with up-to-date technology and a microprocessor system for very precise control of disturbances caused by phase loss, phase swap, phase asymmetry and current asymmetry, voltage increase and decrease, and current increase and decrease, for use in all industrial facilities without the need for a CT, in two models (0.5-15A) with 0.1A accuracy and (1-60A) with 1A accuracy.

Features of the Shiva Amvaj Phase-Load Monitor

  • Complete protection of three-phase devices using a microprocessor system

  • Current control based on the I2t curve

  • Current measurement without a CT, with direct cable pass-through (up to 25mm²)

  • Display of current, set values and error messages

  • Protection against

    • Current increase, decrease and asymmetry

    • Voltage increase, decrease and asymmetry, phase loss and phase sequence error

  • Display capability

    • Voltage

    • Device active time (current flow)

    • Number of current on and off events

  • Automatic reset can be enabled or disabled

  • 10 indicators for signaling

    • OL: Overcurrent ( 0.5-15A),(1-60A)

    • UL: Undercurrent ( adjustable up to 1 unit below OL)¹

    • A%: Current asymmetry (7-100%)

    • OV: Overvoltage

    • UV: Undervoltage

    • V%: Voltage asymmetry

    • OFF: Off delay

    • Normal: Relay state( flashing: ready for Reset)

    • On Delay: On delay or Reset delay(0-240Sec)

    • Delay Start: Initial start time (0-120Sec)²

1. One unit equals 0.1A in the 15A model and 1A in the 60A model. If UL is set to zero, undercurrent detection is disabled.

2. The initial start time is the period after the relay is on and current flows during which undervoltage and current increase are ignored.
