Available Configurations

The SMRT46 is a multipurpose, light-weight, field portable test set capable of testing a wide variety of electro-mechanical, solid-state and microprocessor-based protective relays, motor overload relays and similar protective devices.

The SMRT46 test system has the ability to be manually controlled with Megger’s Smart Touch View Interface™ (STVI). The STVI, with its large, full color, high resolution, TFT LCD touch screen allows the user to perform manual, steady-state and dynamic testing quickly and easily using the manual test screen, as well as using built-in preset test routines for most popular relays (see STVI datasheet for details).

For full automatic testing the SMRT46 may be controlled by Megger Relay Testing Management Software (RTMS). RTMS is a Microsoft® Windows® XP® Service Pack 3/Vista™/7/8/10 compatible software program designed to manage all aspects of protective relay testing using the new Megger SMRT33, (see RTMS datasheet for details).

Features:

  • Small, rugged, lightweight and powerful
  • Intuitive manual operation with Smart Touch View Interface
  • High current, high power output
  • (60 Amps/300 VA rms) per phase
  • 4 Voltage channels, 3 Current channels, with convertible voltage channels provides 1 voltage and 6 currents
  • Dynamic, Transient and GPS Satellite Synchronized End-to-End Testing Capability
  • IEC 61850 Testing Capability

Input Power

  • 100 to 240 Volts AC, 1Ø, 47/63 Hz, 1800 VA.

Outputs

  • All outputs are independent from sudden changes in line voltage and frequency. All outputs are regulated so changes in load impedance do not affect the output. Each output (VIGEN) module consists of one voltage amplifier, and a current amplifier. The voltage amplifier may be converted to a current source. Therefore, one amplifier module may be used to test single phase current differential relays, including harmonic restraint.

Output Current Sources

  • The SMRT46 with three VIGEN modules can provide up to six current sources; three high current/high power, and three convertible voltage channels providing lower current/high power. The per channel output current and power ratings are specified in AC rms values and peak power ratings.

Per Channel Output

  • Output Current:
    • 1 Ampere 15 VA
    • 4 Amperes
    • 15 Amperes
    • 32 Amperes
    • 60 Amperes
    • DC 200 Watts
    • Duty Cycle: 32 Amps Continuous, 60 Amps 1.5 seconds
