China GDDF-10 Multiple Frequency PT Induced WithstVoltage Tester

GDDF-10 Multiple Frequency PT Induced Withstand Voltage Tester
General Information

GDDF-10 is used for checking the vertical insulation between turns, layers, sections and phases of the transformer winding. It is small and light, with stable performance, and also easy to operate.

Features
1. Adopted with advanced electronic technology, with variable frequency regulator.
2. Digitally control of parameter presetting, protection setting, frequency choosing and voltage regulating.
3. PC inserted. Color touch screen, with thermal printer.
4. With a data storage capacity of 3200 sets of data.
5. Optional test frequency of 50Hz, 100Hz, 150Hz and 200Hz.
6. Realtime adjustment for step length. 1V, 2V, 5V and 10V are optional.
7. Internal LC filtering circuit, ensuring low waveform distortion rate.
8. Internal compensation inductance, which compensates the current of tested object capacitance, and improves the loading capacity.
9. It can generate test voltage output of 1, 2, 3, 4 times frequency.
10. With easy wiring and operation. It has lower requirement for power source capacity during on-site test.
