Transformer Testing

•    Measurement of inrush currents, harmonics.
•    Transformer turns ratio.
•    Vector group test.
•    Winding resistance test.
•    Testing of transformer, shunt reactors and capacitors banks.
•    Insulation test of transformer windings and core, and polarization index measurement.
•    Magnetizing current test.
•    Short circuit test (impedance measurement).
•    Magnetic balance test.
•    CT , VT testing.
