The Megger MVCT test set is a lightweight, robust, portable unit capable of testing both current and voltage transformers. At less than 20 lb (10Kg) the MVCT is a highly portable unit that also offers accuracy in testing. Capable of performing saturation, ratio, polarity, winding resistance, and insulation tests on current transformers, the MVCT can also be used for testing metering and protection class voltage/potential transformers. The MVCT provides a microprocessor controlled variable voltage and current output along with precision instrumentation for automatically testing single and multi-ratio CTs and VT’s. The MVCT makes testing CTs easy. It will directly connect to multi ratio CT’s and perform all tests – saturation, ratio and polarity, winding resistance, and insulation – on all taps with the push of a button and without changing leads. This greatly reduces testing time. The MVCT can be controlled via its large, full color, high resolution, sunlight readable TFT LCD touch screen display. This interface allows the user to perform manual and automatic testing quickly and easily using the manual test screen, or by using pre-constructed test routines. The large color display also permits the user to easily read all pertinent data while the test is being performed and provides the ability to view the results when the test is complete. The unit can also be configured to come without a display and thus be controlled via a laptop utilizing PowerDB or with Megger’s existing Smart Touch View Interface™(STVI). Both current transformers and voltage transformers can be tested in their equipment configuration, such as being mounted in transformers, oil circuit breakers or switchgear. It is necessary for the equipment to be completely isolated from the electrical system

The Megger MRCT is a light weight, robust, portable unit used to perform demagnetization, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers. The MRCT automatically calculates ratio errors, saturation curves, and knee points. The MRCT provides a microprocessor-controlled variable voltage and current output and precision instrumentation for automatically testing single and multi ratio CTs, reducing testing time and increasing productivity. The MRCT will directly connect to multi ratio CT’s and perform all tests – saturation, ratio and polarity, winding resistance and insulation – on all taps with the push of a button and without changing leads.

The MRCT can be controlled via Megger’s Smart Touch View Interface (STVI) controller. The STVI controller is a full color, high resolution, LCD touch screen which allows the user to perform manual and automatic testing quickly and easily using the manual test screen, as well as using pre-constructed test routines. The large color display permits the user to easily read all pertinent data while the test is being performed and provides the ability to view the current transformer’s saturation curve. The unit can also be configured to come without a Megger STVI and can be controlled via a laptop with Megger’s PowerDB software.

Current transformers can be tested in their equipment configuration, such as being mounted in transformers, oil circuit breakers or switchgear. It is necessary for the equipment to be completely isolated from the electrical system prior to testing.

As 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.

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 Sverker 650 testing unit, whose design incorporates benefits gleaned from many years of experience in field relay testing, enjoys a well-earned reputation for reliability and convenience.Compact and powerful, it provides all of the functions needed for secondary testing of almost all types of single-phase protection now available on the market.

SVERKER 650 features logical design and construction, and it is extraordinarily easy to learn and use. Its compact design and light weight makes it extremely portable.

Auxiliary equipment for SVERKER 650 includes a test lead set and a rugged transport case. Another useful accessory is the ACA120 voltage source which makes it easier to test directional relays

The SVERKER 750/780 Relay Test Set is the engineer's toolbox. The control panel features a logical layout, still SVERKER 650 users will find it comfortably familiar and will be able to start work right away.

The SVERKER 750/780 features many functions that make relay testing more efficient. For example, its powerful measurement section can display (in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos φ. The voltmeter can also be used as a 2nd ammeter(when testing differential relays for example). All values are presented on a single easy-to-read display.

You can also test directional protective equipment efficiantly by means of the built-in variable voltage source. In SVERKER 780 this has a continuous phase shift function and adjustable frequency as well. Automatic reclosing devices can also be tested – just as easily.

Designed to comply with EU standards and other personal and operational safety standards, SVERKER 750/780 is also equipped with a serial port for communication with personal computers and the PC software SVERKER Win. Since the compact SVERKER weighs only 18 kg (39 lbs), it’s easy to move from site to site.

Two or more SVERKER units can also be synchronized, which allows the user to operate a basic 3-phase test set.

The SVERKER 900 Relay and Substation Test System is the engineer’s ultimate toolbox that addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial applications. The intuitive user interface is presented on the LCD touch screen. It has a powerful combination of current and voltage sources and a versatility of measurement possibilities.

The SVERKER 900 is specifically designed for basic, manual threephase secondary testing of protection devices. In addition, various primary testing can be performed, since the current and voltage sources can be series- and/or parallel connected to allow for up to 105 A AC or 900 VAC output. All three current and four voltage sources can be individually adjusted with respect to amplitude, phase angle and frequency. The fourth voltage source allows for testing of numerical relays that needs a reference voltage simulating. 

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 has the “smart” combination of small size, light weight, with high power.

For full automatic testing the SMRT46 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 test system.

The SMRT410 has the “smart” combination of high compliance voltage and high current output to test all electromechanical, solid-state and microprocessor-based overcurrent relays, including; voltage controlled, voltage restraint and high impedance directional ground overcurrent.

The SMRT410 provides a complete multi-phase test system for commissioning of protection systems. With up to 4 voltage channels and 6 high current channels, the SMRT410 meets every testing need. The SMRT410 VIGEN modules also provide high power in BOTH the voltage and current channels to test virtually all types of protective relays. The SMRT410 test system may be customized by adding the number of Voltage-Current, “VIGEN”, modules needed for specific test applications.
