20% of turbo-generator sets have problem of fire-resistant oil's resistivity surpassing standard in operation.Based on test study in many years
the main causes of resistivity surpassing set standard have been pointed out as follows:(1)unstrict supervision in buying new fire-resistant oil;(2)the fire-resistant oil being polluted by polarized matters;(3)oil temperature in operation was not properly controlled
or partial overtemperature points existing in the system;(4)high water content in the fire-resistant oil.For this
the methods for solving said problems and corresponding countermeasures have been put forward.
