MRCT

The Megger MRCT is a light weight, robust, portable unit used to perform demagnetization, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers. The MRCT automatically calculates ratio errors, saturation curves, and knee points. The MRCT provides a microprocessor-controlled variable voltage and current output and precision instrumentation for automatically testing single and multi ratio CTs, reducing testing time and increasing productivity. The MRCT 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.

The MRCT can be controlled via Megger’s Smart Touch View Interface (STVI) controller. The STVI controller is a full color, high resolution, LCD touch screen which allows the user to perform manual and automatic testing quickly and easily using the manual test screen, as well as using pre-constructed test routines. The large color display permits the user to easily read all pertinent data while the test is being performed and provides the ability to view the current transformer’s saturation curve. The unit can also be configured to come without a Megger STVI and can be controlled via a laptop with Megger’s PowerDB software.

Current transformers can be tested in their equipment configuration, such as being mounted in transformers, oil circuit breakers or switchgear. It is necessary for the equipment to be completely isolated from the electrical system prior to testing.

Features

  • Industry leading test duration using patented simultaneous multi-tap measurements reduces testing time by 20% on multi-tap CT’s
  • Accuracy to support testing of metering and protection class CT
  • Integrated single phase relay test system
  • Grouped testing: demagnetization, knee points, ratios, saturation curves, winding resistance insulation and more
  • Measure all ratio’s and saturation curves on multi-tap CT’s with one lead connection
  • Optional DC excitation technique for testing CTs with kneepoints up to 30 kV
  • Optional Integrated VT and CT test system

MVCT

The Megger MVCT test set is a lightweight, robust, portable unit capable of testing both current and voltage transformers. At less than 20 lb (10Kg) the MVCT 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. The MVCT 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 MVCT 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 also be configured to come without a display and thus be controlled via a laptop utilizing PowerDB or with Megger’s existing Smart Touch View Interface™(STVI). Both current transformers and voltage transformers can be tested in their equipment configuration, such as being mounted in transformers, oil circuit breakers or switchgear. It is necessary for the equipment to be completely isolated from the electrical system

 

Features

  • 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 30 kV
  • CT grouped testing includes demagnetization, knee points, ratios, saturation curves, winding resistances, polarities and phase deviation (on all taps of multi-ratio CTs)
  • VT testing including demagnetization, ratio, winding resistance, polarity and phase deviation
  • Performs secondary burden tests
  • Integrated 1 kV DC insulation test system
