Double Voltage Double Frequency

This test setup is generally used to perform induced voltage test on the transformers. This set up consists of the USED motor and generator combination to develop the required voltage and frequency. Both generating unit and the drive motor are mounted on a common metallic frame. The DVDF Test Set (Double Voltage, Double Frequency) is Introduced The strength of the insulation between transformer turns and other sites is tested using an over voltage test set.

To limit the magnetising current over frequency, double voltage is provided across the L.T. terminals for one minute during this test. With a motor, an alternator, electricity, and a control panel to manage the output voltage, we provide it as a mechanically attached unit. A suitable control panel is created for starting motors, controlling generator output, measuring voltage and current for input and output for all three phases, and protecting circuits and metres.
