Hlpot &resistance test.jpg

The tester is an equipment for measuring withstand voltage, and it intuitively actually quickly and reliably tests a variety of electrical safety performance indicators, such as breakdown voltage, leakage current etc. of equipments under test and it also tests performance of components and the whole machine as AC high voltage source. ET2670A withstand voltage tester is designed according to the International and national safety standard such as IECISOBSVLJIS, and its withstand voltage AC is 0~5kV, leakage current AC is 0.1~20mA. The tester is widely used in measuring safety withstand and leakage current tests for different electrical apparatus, insulation materials, high-low voltage switchgear, low voltage bus, electric machine and components. At the same time, the tester is an integral withstand voltage test equipment for research laboratories and the department of technical supervision.

Test voltage, leakage current test and time are all-digital displayed. And rupturing current can be randomly and continuously set up depending on different safety standards and customers’ requirements that enriches its function. And the leakage current display actual value of testing leakage current and compare how well of withstand voltage between the same products of different bathes or products from different companies.
