HK-507A Insulating Oil Dielectric Breakdown Tester

Oils that combine a high flashpoint with high dielectric strength have long been used as an insulating medium in transformers, switchgear and other electrical apparatus. To ensure that the dielectric strength of the oil does not deteriorate however, proper maintenance is essential, and the basis of proper maintenance is testing.


For many electric equipments used in power system and enterprises, inner insulation is mostly oil-insulated. Oil dielectric strength test is one of the essential routine tests.  


Our HK-507A oil dielectric breakdown tester is the ideal testing device for oil dielectric strength. The test sets are fully automatic. Our products have been used by many power enterprises all over the world.

HK-0308 Air Release Value Apparatus

HK-0308 Air release value apparatus conforms to the ASTM D3427 standard Test Method for Air Release Properties of Petroleum Oils.


It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. This apparatus measures the time for the entrained air content to fall to the relatively low value of 0.2 % volume under a standardized set of test conditions and hence permits the comparison of the ability of oils to separate entrained air under conditions where a separation time is available. The significance of this test method has not been fully established.


However, entrained air can cause sponginess and lack of sensitivity of the control of turbine and hydraulic systems. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high
