Megger SMRT1D Single Phase Relay Test System - Price on application

The Megger SMRT1D is a configurable product - Contact us for pricing

As a standalone unit the Megger SMRT1 and 1D has the “smart” combination of high compliance voltage and high current to test electromechanical, solid-state, and microprocessor-based overcurrent relays. This includes voltage controlled, voltage restraint and directional overcurrent, under/ over voltage, single-phase impedance, single-phase power, directional, synchronising, auto-synchronising, negative sequence under/over voltage, current balance, frequency, volts/hertz, reclosing, thermal, and various other relays.

The Megger SMRT1D test system can be manually controlled with the Integrated on-board display. The on-board display with its large, full colour, high resolution and Wide Viewing Angle Technology bright LCD touch screen display 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 pre-set test routines for most popular relays.

The on-board display on the SMRT1D eliminates the need for a computer when testing almost any type of relay. Menu screens and touch screen function buttons are provided to select the desired test function quickly and easily. Tests results can be saved to the on-board display’s, internal memory for later download to a USB drive to transfer or print test reports. For fully automatic testing every SMRT unit is supplied with Relay Test Management Software (RTMS). There are two different levels of RTMS: Standard and Enhanced. Megger also supports customers using the legacy Advanced Visual Test Software (AVTS).

Features and Benefits

Constant power output – The current amplifier delivers maximum compliance voltage to the load constantly during the test, and range changing is done automatically under load. This ensures better test results and saves time by not having to turn the outputs off to change ranges.

High output current – Provides up 32 A at 200 VA per phase continuous for timing tests and can provide up to 60 A at 319 VA for testing instantaneous overcurrent relays.

PowerV™ voltage amplifier high power output – The SMRT1 and 1D provides a high VA power output on the voltage channel at the lower critical test voltages (from 30 to 150 V). The high burden voltage option in the SMRT, when enabled allows the unit to output up to 1 A at 300 V.

Convertible voltage channel – Provides a second current source for testing single phase current differential relays, including harmonic restraint transformer differential relays. Paralleled with the main current channel to increase output current to 37 A continuous, and up to 75 A for a short time.

High resolution and accuracy – Metered outputs provides extremely high accuracy needed for testing a wide variety of devices. Eliminates uncertainty with setting values, with metered values what you see is what you get.

Steady-state and dynamic testing capability – The SMRT1/1D provides, either through manual control or computer control, both steady-state and dynamic testing of protective relays. This includes programmable waveforms with harmonics.

Output current and voltage sine waves are generated digitally – Outputs do not vary with sudden changes in input voltage or frequency, which increases test accuracy and reduces testing time.

Digital binary input and output – The programmable binary input, and programmable output provide timing and logic operations in real-time with the output voltage and currents. The binary input can be programmed, using Boolean logic, for more complex power system simulations.

Circuit breaker simulator – Binary output provide programmable normally closed or normally open contacts to simulate circuit breaker operation for testing reclosing relays. Sequence of operation, timing, and lockout are easily tested.

Performs transient tests – Perform acceptance or troubleshooting tests by replaying digitally recorded faults or EMTP/ATP simulations in the IEEE C37.111/IEC 60255-24, COMTRADE Standard format.

Perform end-to-end tests – Using the RTMS Sequencer test; with a Megger MGTR GPS satellite receiver (or suitable IRIG-B time code source input into Binary Input #1), the SMRT1/1D performs satellite synchronised end-to-end tests.

Wide-ranging output frequency – The output frequency of the current and voltage outputs can be set for any frequency from DC to 1 kHz. Popular test frequencies such as 16.66, 25, 33, 50, 60, 100, 120, 125, 150, 180, 250, 300, and 400 Hz are easily set and controlled.

Two Ethernet ports – PC/IN Ethernet port is the primary PC connection port. It is also used when chaining multiple SMRT units together. The 61850/OUT Ethernet port is primarily used to interconnect multiple SMRT units together for synchronous multi-unit operation, or it may be used to connect to the IEC 61850 substation bus.

IEC 61850 and Megger GOOSE Configurator – With the IEC 61850 GOOSE option enabled in the SMRT hardware the Megger GOOSE Configurator (MGC) provides mapping of the binary inputs and outputs of the SMRT test set to the desired GOOSE messages. The GOOSE messages are read from available SCL (Substation Configuration Language) files or may be automatically detected by scanning the substation network in search of available published GOOSE messages.

IEC 61850 9-2 LE and Megger Sampled Values Analyser (SVA) – With IEC 61850 9-2 LE Sampled Values option enabled in the SMRT hardware Sampled Values Analyser (SVA) is used as a testing tool that provides the ability to configure a maximum of three Sampled Value (SV) streams compliant with first edition of IEC 61850 9-2 LE to be used in process bus applications for digital substations.

Low-level Rogowski mode – In the Low-level Rogowski mode, the current channels will convert from a current source to a millivolt source. This will allow the current channel to simulate a low-level voltage source from a Rogowski coil.

Low-level output capability – The current generators can provide very low current outputs ranging from 0 to 50 mA full scale or be enabled to provide a voltage output simulating a Rogowski output. In Rogowski mode the current channel will change from a current source to a voltage source, this will allow the current channel to simulate a low-level voltage source from a Rogowski coil.

Universal input voltage – Operation from 90 to 264 VAC, 50/60 Hz.

Immediate error indication – Audible and visual alarms indicate when amplitude or waveforms of the outputs are in error.

Bluetooth – Optional Bluetooth provides more flexibility.

Variable voltage threshold – The variable voltage threshold will either start or stop the timer. With a programmable range from 5 to 150 volts AC/DC.

Open communication architecture – The SMRT units can be used with third party software for more flexible automated control.
