Frequently Questions

Just let us know your voltage class, sectional arear of the cable. How long is the tested cable? will you also test electrical apparatus, GIS? Will you also test main substation? A good resonant test system must be with more output, larger currency, more exciting transformer windings. It must be capable of a full withstanding testing. As a leading factory of hipot tester, Hertz resonant test systems can find the frequency within 45 seconds.
We offer all round service to our customers. We offer product choosing guidance before order and worry free service after sales. Just let us know your testing condition including voltage class, power frequency, tested item, and tested purpose, then our professional techinician will teach you from tester choosing to installation and commission.
1, distance tester: 100km testing distance. temporary waveform storage for comparation analysing three testing methods the testing tolerance is within 1 meter 2 cable locating: acoustic-magnetic delay function noise avoiding 3 pipeline identifier: can test path, direction and depth strong anti interference 14 meters testing depth suitable for different environmental such as grass land, cement road

We introduce VLF. VLF is the most commen AC withstand testers. Just let us know your voltage class, your tested items, and testing capacitance, and then we will choose a suitable VLF for you
Transformer test bench is used for integrated testing of transformers. Just let us know the testing condition for each transformer(which will be shown in a data sheet). Tell us your test purpose and then we will design a suitable transformer test bench for you
Generally, we can deliver the goods within 7 days for standard testers. For customized products, we need 15 to 20 days to prepare the products. For resonant test system, we need 2 months.
