Relay Test Sets
The Smart Solution For Protective Relay Testing. Smaller, lighter and with a higher output power than any other comparable three-phase instrument in the world, Megger's new SMRT 36 smart protective relay test set is ideally suited not only for testing today's installations and legacy plant, but also for meeting the future challenges associated with testing the smart grid.
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 over current relays, including voltage controlled, voltage restraint and directional over current; 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, see the Applications Guide for more.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 colour, 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.
Shortest test duration in the industry: Our present system allows simultaneous measurement on all taps during CT saturation, ratio and polarity, winding resistance and insulation resistance testing. The MRCT eliminates the need to test each tap sequentially and independently, thereby reducing testing time by up to 50%
Portable and lightweight: At 35lbs, the MRCT is the smallest and lightest secondary voltage injection unit on the market.
One-button automated test mode: Automatically perform preset test routines on all taps without changing leads, and at a single push of a button.
Intuitive manual control: In addition to fully automated testing, the MRCT also allows field users to manually configure all test settings through a user-friendly touchscreen interface.
Visualise results instantly: Multiple instantaneous saturation curves and knee points are calculated and plotted on the fly as the tests are being performed.
Easy test data management: All test results and saturation curves can be cataloged and stored within the MRCT. Test files are saved in a versatile format and can be exported into data management software such as PowerDB.
The SMRT43 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 SMRT43 has the "smart" combination of small size, light weight, with high power.
The SMRT43 test system has the ability to be manually controlled with Megger's Smart Touch View Interface™ (STVI) handheld controller running the new RTMS, Relay Testing Management Software. The STVI, with its large, full colour, 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 pre-set test routines for most popular relays.
Megger's New SMRT46D Multi-phase Relay Test System expands your testing abilities by adding a 4th voltage channel, giving you another game-changing tool to help you get your job done faster and more efficiently.
A fourth voltage channel can provide a synchronizing reference voltage, or serve as a battery simulator. With the voltage channels converted to currents, a three channel unit can provide 6 currents for testing three phase current differential relays, including harmonic restraint transformer differential relays
3 Phase Relay Tester
The innovative Sverker 900 test set, which has been conceived as an engineer’s “multi-function testbox” for protection testing. It features an intuitive user interface so that a PC is not required to operate the instrument.
It centres around a touchscreen that provides access to a wide range of pre-configured virtual test instruments, allowing the required test function to be selected quickly and easily. Full manual control and configuration are also supported and, in addition to the touchscreen, the instrument is provided with a large rotary knob that can be configured as required to control the current and voltage generators.
