Product Name: High Voltage Tester

Product Description

SIGMA High voltage breakdown tester are useful for measurement of breakdown (flashover) voltage of electrical components, insulation materials instruments, transformers, etc. can be used to ascertain quality of insulation material before planning their usage in electrical applications. The front panel incorporates all controls for operation of the unit. Easy to use test probes with micro-switch supplied to connect the output high voltage to the device under test.

AC High Current Primary Current Injection Test Set, Secondary Injection Test and Other Electrical High Voltage Test Equipment in INDIA. In the last 36 Years, Through Continuous Aspirations, 'RE' has earned the Goodwill of Quality Control Engineers............

HIGH VOLTAGE TEST The high voltage test (also called dielectric strength test or hipot test) can be made in AC or DC. If the high voltage test is made in DC, it is then combined with insulation ; if the high voltage test is made in AC, it is then, this is then, more stressful for the sample and made according to the sketch below. Measurement of high voltage test under alternating current is performed using an alternating voltage (50Hz) adjustable to an effective 50V to 1,500V. As is the case with direct current, the high voltage test detects any sudden rise of current up to a programmed threshold. The short circuit test is maintained by default. The rise time is more than 500 ms and the application time at least one period. Warning: The high voltage test under alternating current is penalised by the capacitive value of the tested equipment. It must be remembered that the generator power is limited to 5 mA.
