Page 4: Overview
I. 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. -

Page 11: Precautions
VI. Precautions 1. The selection, placing and electrode distance of the oil sample before testing, shall be accord with national standards and industry standards. 2. The operators or other personnel are strictly forbidden to touch the casing after the power is switched on, to avoid accidents. 3. - Page 12 ⑶ Use petroleum ether (other organic solvents are forbidden) to clean three times. Each time shall follow the bellow procedures: ① Pour the petroleum ether into the oil cup till the cup is 1/4～1/3 full. ② Cover the cup mouth with a piece of glass cleaned by petroleum ether. Shake the cup evenly for one minute with certain force.
