Datasheet
The Megger MVCT VT and CT Analyzer is a portable current and voltage transformer test set with an output power of 300VA, an input range from 0 to 2/10/50/300V, and a current measurement range of 0 to 1.0A. CT Testing applications for the MVCT test set include saturation tests--with the single push of a button, the MVCT will perform a saturation test in compliance with either IEEE C57.13.1, IEC 60044-1, IEC 60044-6 or IEC 61869 standards. Polarity of current transformers is easily discovered through ratio, polarity and burden testing, comparing voltage applied to the first and second windings and indicating results with a simple "Correct" or "Incorrect." The Megger MVCT also conducts winding resistance, demagnetization and CT burden testing. Inductive VT tests are supported as well, with VT ratio and polarity, winding resistance and insulation testing also possible. The Megger 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 Megger MVCT is 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. Megger MVCT units can also be be controlled via a laptop utilizing PowerDB or with Megger’s existing Smart Touch View Interface™ (STVI).
