Megger MPRT8445 MGR-MPRT8445 MPRT Megger Relay Test Set Three Phase
The 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 incorporates the latest in Digital Signal Processor (DSP)
and microprocessor-based technology, to provide a powerful, easy to use relay
The Smart Touch View Interface (STVI) touch screen allows the user to perform
manual, steady-state and dynamic testing quickly and easily using the Manual
or Sequencer test screens, as well as using built-in preset test routines for
most popular relays. Ergonomically designed for either right or left hand
operation using the rubber cushion grips, the centrally located control knob,
and the touch screen, the STVI is extremely easy to use. Use the new built-in
stand for single-handed operation. The STVI uses a standard Ethernet cable,
and Power Over Ethernet (POE) operation. The STVI includes non-volatile
built-in data storage for saving tests and test results and it incorporates a
large, easy to
read Full Color high resolution, high definition, TFT LCD touchscreen display,
which displays metered values such as AC and DC Amperes, AC and DC Volts, and
Time in both seconds and cycles. Depending on the type of test selected, other
values may be displayed, such as Ohms, Watts, Phase Angle, or Frequency.
A USB port is provided for transferring test results to your PC.
*The MPRT8445 provides up 30 Amps at 200 VA per phase continuous, or up to 45
Amperes at 300 VA with a 1.5 second duty cycle. Four current amplifiers can be
paralleled to provide a maximum of 180 Amperes at 1,200 VA for testing all
instantaneous overcurrent relays.
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.
