Megger Relay Test System

SMRT36 with optional Transducer hardware

DESCRIPTION

For size, weight, and features the SMRT36 is conceivably the smallest, lightest, highest output powered, complete three phase relay test system in the world today. The test system may be customized by adding the number of Voltage-Current, “VIGEN”, modules needed for specific test applications. The SMRT36 has the “smart” combination of high compliance voltage and high current to test all electromechanical, solid-state and microprocessor-based overcurrent relays, including voltage controlled, voltage restraint and directional overcurrent.

The SMRT36 with three VIGEN Modules provides a complete threephase test system for commissioning of three phase protection systems. With the voltage channels converted to currents, the same unit can provide 6-phase current. The SMRT36 VIGEN modules also provide high power in BOTH the voltage and current channels to test virtually all types of protective relays.

Fully automated testing using

AVTS Software

The SMRT36 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 STVI for download to a memory stick to transfer or print test reports.

For full automatic testing the SMRT36 may be controlled by Megger Advanced Visual Test Software (AVTS). AVTS is a Microsoft Windows® XP®/Vista™/7 compatible software program designed to manage all aspects of protective relay testing using the new Megger SMRT.

APPLICATIONS

Each 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 insures maximum compliance voltage to load at all times. Three currents in parallel provide up to 180 Amps @ 900 VA for instantaneous tests. With a maximum compliance voltage of 50 Volts per phase, with just two channels in series provides 100 Volts of compliance voltage to test high impedance relays.

SMRT36 with STVI

SMRT36

Megger Relay Test System

Each voltage channel can provide variable outputs of 0- 30/150/ 300 Volts at 150 VA of output power, and has a unique flat power curve from 30 to 150 Volts insuring maximum output power to the load at all times. With the voltage channel converted to current, a three channel unit can provide 6 currents for testing three phase current differential relays, including harmonic restraint transformer differential relays.

Using the Ethernet ports, the SMRT36 is literally a “plug-andplay” unit, where voltage and current outputs can be seamlessly synchronized with other SMRT units outputs for testing more complex test applications such as back-to-back tests, or 9 up to12 phase current test applications.

FEATURES AND BENEFITS

Constant Power Output – New higher powered Voltage-Current amplifiers. The current amplifier delivers maximum compliance voltage to the load constantly during the test, and range changing is done automatically under load. This insures better test results, and saves time by not having to turn the outputs off to change ranges. Constant power output in many cases eliminates the need to parallel or series current channels together to test high burden relays.

High Output Current – Provides up 30 Amps at 200 VA per phase continuous, or up to 60 Amperes at 300 VA with a 1.5 second duty cycle. The three current amplifiers can be paralleled to provide a maximum of 180 Amperes at 900 VA, for testing all instantaneous overcurrent relays.

New PowerVTM Voltage Amplifier High Power Output – The SMRT provides a new higher VA power output on the voltage channel at the lower critical test voltages (from 30 to 150 Volts). Customers who want to test a panel of relays at one time find it impossible using lower VA rated voltage.

Convertible Voltage Channels – With a 3 channel SMRT36 unit, convertible channels in conjunction with the three main current channels, provides 6 currents for testing three phase current differential relays. With all six currents in parallel the unit can provide a maximum single phase output of 225 Amperes for short durations.

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

Steady-State and Dynamic testing capability – The SMRT36 provides, either through manual control or computer control, both steady-state and dynamic testing of protective relays. This includes programmable waveforms with dc offset and 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.

Modular design – Output modules plug-in and out easily for system re-configuration and maintenance.

Built-in Transducer Testing Capability – The SMRT36P incorporates high accuracy amplifiers, an optional transducer DC input and test algorithms to test transducers easily and effectively.

Digital binary inputs and outputs – The programmable binary inputs, and programmable outputs provide timing and logic operations in real-time with the output voltage and currents. Binary Inputs can be programmed, using Boolean logic, for more complex power system simulations. This provides a low cost, closed loop, power system simulator.

Circuit breaker simulator – Binary outputs provide programmable normally closed and 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, COMTRADE Standard format.

Perform End-to-End tests – Using AVTS software and a portable GPS satellite receiver, the SMRT performs satellite-synchronized endto-end dynamic multi-state or playback transient COMTRADE files either for commissioning or troubleshooting tests.

Wide-ranging output frequency – The output frequency of the current and voltage channels 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. Multi-purpose test system saves time and money.

USB 2.0 interface port – The USB port provides a PC interface for automated control of the SMRT unit. Also provides secure isolation when testing IEC 61850 devices (for customers who require secure isolation from their IEC 61850 substation bus).

Three Ethernet ports – PC/OUT Ethernet Port is the primary PC connection port. The IN/IEC61850 Ethernet Port provides interface to multiple SMRT units, and may be used to connect to the IEC 61850 substation bus. The OUT Ethernet Port is primarily used to interconnect multiple SMRT units together for synchronous multiunit operation. The STVI PoE (Power over Ethernet) port and is used to connect to the STVI.

Bluetooth – Optional Bluetooth provides more flexibility. A wireless interface between the PC and SMRT, in conjunction with the SMRT IEC 61850 Ethernet port, provides the isolation required for a secure substation access interface between the SMRT and the IEC 61850 substation network.

Universal input voltage – Operation from 90 to 264 Vac, 50/60 Hz, the SMRT can use virtually any standard source in the world.

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

Optional Transducer Testing Capability – This optional hardware feature (see Ordering Information) provides transducer DC Inputs to test transducers easily and effectively. The STVI software is designed to automatically recognize the Transducer DC Inputs, and thus provide the Transducer Test Screen when selected. AVTS software comes standard with Transducer Test Modules, which will provide automatic transducer test capability in conjunction with the optional hardware.

Input Power

The input voltage rating varies depending upon the style number. Universal units, the input voltage may be from 100 to 240 VAC, ± 10%, 50/60 Hertz. CE Marked units, the input voltage may be from 220 to 240 VAC, ± 10%, 50/60 Hertz. Total maximum output power will be limited for CE marked units . Input current required varies with the number of output modules in use, load, and input voltage value. With three VIGENS, the maximum input power is 1800VA.
