SMRT46 & SMRT46D

Multi-Phase Relay Testers

The SMRT46 and 46D are multipurpose, lightweight, field portable test sets capable of testing various electromechanical, solid-state and microprocessor-based protective relays, motor overload relays, and similar protective devices.

You can manually control the SMRT46 and 46D test systems with Megger’s new Smart Touch View Interface (STVI). The SMRT46D 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 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 SMRT46.

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 SMRT46 or SMRT46D 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.
