Double Voltage Double Frequency Transformer Test Set

DVDF Test Set Double Voltage Double Frequency Test Set DVDF Test Set is Induced Over Voltage Test Set is used for testing the strength of insulation between turns and between other points of the transformers. For this test Double Voltage is applied across L.T. terminals for one minute, and to limit the magnetising current over frequency is utilised. We supply it is as mechanically coupled unit having motor and Alternator with power and control panel to regulate the output voltage. A suitable control panel is design for motor starting, generator output control, measurement of all three phases, voltage and current for input and output with protection circuit and meters.
