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.
general specifications that you might find in a typical DVDF test set panel:
Input voltage: Typically rated for 440 VAC 3 phase input.
Output voltage: Variable output voltage up to 866 Volt or Higher , depending on the application.
Output frequency: Adjustable frequency up to 100 Hz, depending on the application.
Control system: Include Digital kv Meter, Frequency meter, Timer and analogue Ameter for indication purpose. A Star delta Starter for smooth Opration.
Safety features: May include various safety interlocks, ground fault detection, over-current protection, and other safety features to protect the operator and the equipment being tested.
Enclosure: Typically housed in a sturdy metal enclosure with handles for easy transportation and storage.
Size and weight: The size and weight of a DVDF test set panel can vary widely depending on the output voltage and frequency rating, as well as Requirments and specific model.
Again, these specifications are just a general guide and can vary depending on the specific model and manufacturer of the DVDF test set panel.
