DVDF Test Set 

Double Voltage Double Frequency Test Set

The Double Voltage Double Frequency (DVDF) Test Set Panel is a piece of electrical testing equipment used to verify the insulation and dielectric strength of high voltage equipment, such as transformers and generators.

The DVDF test involves applying a voltage twice the rated voltage of the equipment being tested, while also increasing the frequency of the power supply to twice the normal operating frequency. This test is performed to ensure that the equipment can withstand such extreme conditions without breaking down.

The DVDF Test Set Panel typically includes a high voltage transformer, a variable frequency generator, a voltage regulator, and various safety features to protect the operator and the equipment being tested. The panel may also include a digital display to monitor the voltage and frequency levels during the test.

The DVDF test is an important part of routine maintenance and testing of high voltage equipment to ensure safe and reliable operation.
