Megger MCT1600B Current Transformer Test Set

Megger MCT1600B Current Transformer Test Set


Megger MCT1600B test is a lightweight, portable unit for shop and field testing of current transformers using IEEE C57.13.1 method. The unit performs excitation, ratio and polarity test by providing a variable output voltage up to 1600 V AC. It will calculate the rated knee point in compliance with IEEE C57.13.1, IEC 60044-1, and IEC 60044-6. MCT1600B test set provides the flexibility of both automatic as well as manual testing. It utilizes the latest DSP technology for testing single and multi-ratio CT’s. The test set can also perform DC insulation resistance test on CT’s to verify the condition of winding to winding and winding to ground insulation.

All three, excitation, ratio and polarity tests can be performed with same connection settings without changing any leads. Current Transformers can be tested in their equipment configuration, such as being mounted in transformers, oil circuit breakers or switchgear. This eliminates the need to remove CT’s from switchgear. It is necessary for the equipment to be deenergized and totally isolated from the electrical system prior to testing.

MCT1600B performs the tests on CT’s to assure that CT’s are of marked ratio and polarity and would perform satisfactorily as designed once put in service. Excitation and burden test ensures that CT’s are of correct accuracy rating and is capable of supplying the known current at stated accuracy. The results obtained from ratio, polarity and excitation tests can be compared with name plate data and manufacturer’s curve to verify the accuracy of the CT under test. The results of the test are displayed on 6.5 inch daylight readable color LCD screen. Ratio and polarity test results can be read right off the screen without any need for calculations. Multiple saturation curves with knee points are shown on the same display for comparison and analysis purpose.

MCT1600B can be operated either stand alone or remotely through computer using Power DB lite software. All the test results can either be stored to unit’s internal memory or can be transferred to computer using a thumb drive, through one of the available USB port on the unit.
