Megger MPRT8445 Three Phase Protective Relay Test System

Megger MPRT8445 Three Phase Protective Relay Test System

The Megger MPRT8445 is a multipurpose, light-weight, field portable test set. The unit is capable of testing a wide variety of electro-mechanical, solid-state and microprocessor-based protective relays, small molded case circuit breakers, motor overload relays and similar protective devices. The Megger MPRT8445 Three Phase Protective Relay Test System may be customized by adding the number of Voltage-Current, “VIGEN”, modules needed for specific test applications.

For electric utility use, the Megger MPRT8445 with three VI Modules provides complete three-phase testing of three-phase impedance, directional power, negative sequence overcurrent and other devices that require a three-phase four-wire wye connected source. Each current channel is rated for 30 Amps @ 200 VA continuous, up to 45 Amps @ 300 VA for short durations.

For testing relay panels or electromechanical relays, it has a unique flat power curve from 4 to 30 Amps that insures maximum compliance voltage to the load at all times. Smart Touch View Interface™ (STVI) Multi-colored graphics with intuitive navigation Enhanced dynamic test capabilities Built-in test report generator High current output – 45 Amps at 300 VA per phase Low current accuracy – currents below 100 mA Convertible voltage channels – 15 Amps at 120 VA Lighter weight unit – up to 15% weight reduction Open communication architecture for use with third-party software programs
