SMRT46R multi-phase relay tester

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.
