AC and DC Dielectric Breakdown Test System

The D149-DI Series of AC Dielectric Breakdown Testers represents a new level of sophistication, flexibility, and accuracy in breakdown voltage testing. Each unit is equipped with a new standard embedded firmware controller that is internally programmed to perform the ASTM D149 short-time test, step-by-step test and slow rate-of-rise test as well as the tests procedures in the IEC60243-1 and IEC60243-2. This unit can also be easily programmed to perform variations of these test sequences. The voltmeter circuit continually samples each waveform to determine the breakdown voltage with the highest accuracy. The operator can control all test parameters as required. When testing is complete, all breakdown information for that series of test samples are automatically recorded. Standard units are available in 30kV, 50kV, 75kV and 100kV AC/DC for a wide variety of applications.
