GDTF-4500/750 is specially designed for AC withstand voltage test for 400kV or below switch, GIS, instrument transformers and neutral point of main transformers.
The system includes Variable frequency power supply, exciting transformer, reactor and capacitive voltage divider.


Features

1. With the protection function of over-voltage, over-current, zero-start, system detune (flashover). Over-voltage, over-current protection value can be set accordingly to user's need. Flashover protection starts when flashover and the flashover voltage value will be recorded for testing analysis.

2.The unit piece of the device is light, suitable for field use.

3.There are three kinds of working mode for user choosing according to on-site condition.
Automatic mode, Manual mode, Automatic tuning manual boosting mode.

4. Data can be stored, and the stored data No. are figures which is easy for identification and searching.

5. Frequency starting point can be set in the specified scope when the device sweep frequency automatically, sweep frequency direction can be selected upward or downward, meanwhile LCD displays the scanning curve, which is convenient to know if the resonant point found or not intuitively.

6. With DSP technology, which can increase or decrease functions and updated accordingly to the user's need, it also makes the human-machine interface more friendly.
