Product Description

Power-Frequency Partial Discharge Pd Hipot Tester Lab Equipment Testing Equipment Laboratory Instruments

Summary
Transformer partial discharge detection device(sf6 high voltage test set) is a necessary test device for power equipment detection and preventive test.
Because of the sf6 high voltage test set excellent insulation and arc extinguishing performance and nonflammability, the six sulfur fluoride gas has been widely applied as a new insulating medium.
After years of efforts, our company has successfully developed a partial discharge detection device for transformers. Compared with the traditional oil immersion light test transformer, this series of the high voltage test set reduce the weight by 20% - 60% (depending on the voltage and capacity grade), and without oil pollution, the voltage level of the single test transformer can reach 300KV. Due to the adoption of the new production technology, the technical performance of the product has been greatly improved, especially for field work and frequent mobile working conditions.
