50KV Very Low Frequency Test Set For Cable , VLF Cable Tester , HV Test , Generator Insulation

I. Application :

Model VLF-50KV/0.1Hz is designed to perform on-site withstand voltage test with very-low frequency test frequency for power generators or 35KV and below XLPE power cable.Compared with Hipot test set at main power frequency, VLF HV Test Set just needs much small test power capacity(About 1/500 in theory). Its size and weight also is decreased greatly. Specially the appearance of surveillance can discover the generator insulation abnormal phenomena such as surface corona, discharge and so on.

VLF hipot tester combines modern advanced digital variable frequency technology and micro computer control together, therefore, it can realize the full automatic voltage boost, stepdown, measurement and protection as well as the manual intervention in the process of automatic voltage boost. The full electronic design ensures the small size and light weight. The big LCD screen ensures the clear and visual display, and can display the output wave form. The printer outputs test reports

The test set consists of a control box, one HV boosters, a compensation capacitor and a discharge rod.Based on electronic frequency conversion and microprocessor controlled technology, it has excellent performance on cable or generator testing.

III. Technical Feature

Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.
Overvoltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself, the actuation time is less than 20ms.
Overcurrent protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 20ms.
A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.
