The transformer oil bdv tester unit is for automatically testing the breadkown voltage or dielectric strength of the insulation oil upto 60kv or 80kv or 100kv. Wooden case
OVERVIEW Many power systems, railway systems, large-scale petrochemical plants and enterprises have a lot of electrical equipment whose internal insulation are mostly oil filled insulation type, and therefore, test on insulating oil dielectric strength is common and necessary. To meet the needs of the market, we have developed and produced a series of insulating oil dielectric strength testers according to national standard GB T507-2002, industry standard DL429.9 91 and the latest Electric Power Industry Standard DL T846.7-2004 by ourselves. This instrument, by using a single chip microcomputer as the core, can operate in full automation with high accuracy, greatly improving work efficiency and reducing the labor intensity of workers. Moreover, it is small in size and convenient to carry.
