DescriptionMegger SMRT1 Single Phase Relay Test System
Key FeaturesSmall, rugged, lightweight, and powerful Operate with or without a computer Intuitive manual operation with Smart Touch View Interface High current, high power (75 Amps/400 VA RMS) Network interface provides IEC 61850 test capabilities Fully automated testing using AVTS software
OverviewAs a stand-alone unit the SMRT1 has the “smart” combination of high compliance voltage and high current to test electromechanical, solid-state, and microprocessor-based overcurrent relays, including voltage controlled, voltage restraint and directional overcurrent; test under/over voltage, single-phase impedance, single-phase power, directional, synchronizing, auto-synchronizing, negative sequence under/over voltage, current balance, frequency, volts/hertz, reclosing, thermal, and various other relays, see the Applications Guide for more.The SMRT1 test system has the ability to be manually controlled with Megger’s new 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.The STVI eliminates the need for a computer when testing virtually all types of relays. Menu screens and touch screen function buttons are provided to quickly and easily select the desired test function. Tests results can be saved to the PowerDBTM ONBOARD for download to a memory stick to transfer or print test reports. For full automatic testing, the SMRT1 may be controlled by Megger Advanced Visual Test Software (AVTS). AVTS is a Microsoft® Windows® XP®/Vista™/7/8 compatible software program designed to manage all aspects of protective relay testing using the new Megger SMRT.
Typical ApplicationsThe current channel is rated for 30 Amps @ 200 VA continuous, up to 60 Amps @ 300 VA for short durations. It has a unique flat power curve from 4 to 30 Amps that ensure maximum compliance voltage to load at all times. With a high compliance voltage of 50 Volts, the SMRT1 has the capability to test high impedance overcurrent relays.The voltage channel can provide a variable output of 0- 30/150/300 Volts at 150 VA of output power, and has a unique flat power curve from 30 to 150 Volts ensuring maximum output power to the load at all times. With the voltage channel converted to current, it can perform minimum operating point, slope, and timing on current differential relays, including harmonic restraint transformer differential relays (which can be tested one phase at a time).It is also designed to operate in conjunction with other SMRT family units. Using the Ethernet ports, SMRT1 is literally a “plug-and-play” unit, where voltage and current outputs can be seamlessly synchronized with other SMRT unit's voltage and current outputs for testing more complex relays like three-phase directional power, distance, loss of excitation, or 6, 9 up to12 phase current test applications.
