Megger MVCT VT and CT Analyser


  • Ability to test both VT and CT 
  • Easy to use one-button automated test plans 
  • Industry leading test duration using patented simultaneous tap measurements 
  • Smallest and lightest unit on the market 
  • CT kneepoints up to 30kV 
  • CT grouped testing includes demagnetisation, knee points, ratios, saturation curves, winding resistances, polarities and phase deviation (on all taps of multi-ratio CTs) 
  • VT testing including demagnetisation, ratio, winding resistance, polarity and phase deviation 
  • Performs secondary burden tests 
  • Integrated 1 kV DC insulation test system 

The Megger MVCT test set is a lightweight, robust, portable unit capable of testing both current and voltage transformers. At less than 10kg it 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. It 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 instrument 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 be configured to come without a display and be controlled via a laptop utilizing PowerDB or with Megger’s existing Smart Touch View Interface™(STVI).
