Insulating Oil Dielectric Strength Tester H507N1
H507N1 In power systems, railway systems, and large petrochemical plants and mines, there are numerous electrical equipment whose internal insulation is mostly oil-immersed. The dielectric strength of insulating oil is a routine test that must be performed. To meet market demands, our company has independently developed and produced a series of insulating oil dielectric strength testers based on the national standard GB/T507-2002, industry standard DL429.9-91, and the latest power industry standard DL/T846.7-2004. This instrument uses a single-chip microcomputer as its core, achieving full automation of testing, high measurement accuracy, greatly improving work efficiency, and significantly reducing the labor intensity of staff.
