The SMRT46R is a multipurpose, lightweight, field portable test set capable of testing various electromechanical, solid-state and microprocessor-based protective relays, motor overload relays, and similar protective devices.
You can manually control the SMRT46R test system with Megger’s new Smart Touch View Interface (STVI). The SMRT46R has this feature built-in, enabling it to be used without a PC via an intuitive, high-resolution graphic touch screen, whereas the SMRT46 requires an external device.
The SMRT46R has the “smart” combination of being both small and light weight, while also providing high power. The SMRT46R has a new case design, with improved distributed power supplies for additional reliability as well is a larger on-board display and additional memory. The SMRT46R test system can be manually controlled with the integrated onboard display on the SMRT46R running the new RTMS, Relay Test Management Software.
The STVI is a controller loaded with Megger’s user interface software. Its large, full colour, high resolution, TFT LCD touch screen allows you to perform manual, steady-state, and dynamic testing quickly and easily using the manual test screen and built-in preset test routines for the most popular relays. Menu screens and touch screen function buttons are provided to quickly and easily select the desired test function. Test results can be saved to the STVI for download to a USB drive to transfer or print test reports.
Both instruments can be placed under full computer control via the Advanced Visual Testing Software (AVTS) or the RTMS running on a PC. AVTS is a Microsoft Windows XP/Vista/7/8/10 compatible software program designed to manage all aspects of protective relay testing using the Megger SMRT46R.
The test system may also be customised by adding the number of voltage-current modules, called VIGEN modules, needed for specific test applications with a maximum of three channels. For example, the SMRT46R with three VIGEN Modules provides complete three-phase testing of three-phase impedance, directional power, negative sequence overcurrent and other devices that require a three-phase four-wire wye-connected source. The fourth voltage channel provides an AC reference/synchronising/polarising voltage, or a DC battery simulator voltage source.
The SMRT410 and 410D Megger relay test system is a multipurpose, lightweight, field portable test set capable of testing a wide variety of electromechanical, solid state, and microprocessor-based protective relays, motor overload relays, and similar protective devices. With up to 4 voltage channels and 6 high current channels, the SMRT410 meets your every testing need, providing you with a complete multi-phase test system for commissioning protection systems.
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 can convert the voltage channels into current channels so 10 current channels are available. All SMRT test sets can be daisy-chained where all channels are time synchronised and controlled as one system to cope with extreme test applications, ie large busbar protection systems or simultaneous injection in several Merging Units.
The SMRT410 test system can be manually controlled with Megger’s Smart Touch View Interface (STVI) or with the Onboard display of the SMRT410D. The STVI-10 is Megger’s second generation of automatic/semi-automatic and manual user interface used with the SMRT family of products. With its large, full colour, high resolution, TFT LCD touch screen, it allows you 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 displays metered values such as AC and DC Amperes, AC and DC Volts, and time in both seconds and cycles. Depending on the type of test selected, other values may be displayed, such as phase angle, frequency, ohms, watts, VA, or power factor/dissipation factor. 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 USB drive to transfer or print test reports.
For full automatic testing, the SMRT410 can also be placed under full computer control via the Relay Test Management Software (RTMS) running on a PC. RTMS is a Microsoft Windows XP/Vista/7/8/10 compatible software program designed to manage all aspects of protective relay testing using the Megger SMRT410.
The SVERKER 750 and SVERKER 780 relay test sets are the engineer's toolbox. The control panel features a logical layout, so SVERKER 650 users will find it comfortably familiar and will be able to start work right away. These instruments are intended primarily for secondary testing of protective relay equipment. Virtually all types of single-phase protection can be tested. You can also test three-phase protection by testing one phase at a time, as well as a number of protective relay systems that require phase shifting, and automatic reclosing devices.
These instruments feature many functions that make relay testing more efficient. For example, they have a powerful measurement section that 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 second 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 efficiently by means of the built-in variable voltage source. In the SVERKER 780, this has a continuous phase shift function and adjustable frequency as well, and automatic reclosing devices can also be tested just as easily.
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 synchronised, which allows you to operate a basic three-phase test set.
Designed to comply with EU standards and other personal and operational safety standards, the SVERKER 750 and SVERKER 780 are also equipped with a serial port for communication with personal computers and the PC software SVERKER Win.
The SVERKER 650 relay test set has been designed to incorporate the benefits gleaned from many years of experience in field relay testing. Compact and powerful, this instrument has a well-earned reputation for reliability and convenience and it provides all of the functions needed for primary and secondary testing. Virtually all types of single-phase protection can be tested. You can also test three-phase protection by testing one phase at a time, as well as a number of protective relay systems that require phase shifting.
The SVERKER 650 features logical design and construction, is extraordinarily easy to learn and use, and its compact design and light weight make 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 650 is ideal for use in high voltage substations and industrial environments. The built-in capacitor provides phase shift when testing directional protective relays and a set of resistors can be used to divide voltages.
The FREJA 546R is a multi-purpose, lightweight, 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 FREJA546R has the “smart” combination of being both small and light weight, while also providing high power. The FREJA 546R has a new case design, with improved distributed power supplies for additional reliability as well as a larger on-board display and additional memory.
