I. Application :
Model VLF-80KV/0.1Hz is designed to perform on-site withstand voltage test with very-low frequency technology 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.
The test set consists of a control box, two HV boosters, a compensation capacitor and a discharge rod.Based on electronic frequency conversion and microprocessor controlled technology, it has excellent performance.
It is prohibited to boost voltage without load, or to connect with resistive load. If the specimen capacitance is less than 0.05uF, the test set output waveform will be bad. For better performance, optional capacitor is necessary to connect.
Until now , the designed test set also forms many different serialized model according to different withstand test applications through HV booster number of configurations in each set, The alike model can see other typical model at following clause.
