How to Choose the Best Hipot Tester
Selecting the right hipot tester depends on your voltage range, expected current output, safety requirements, and test environment. Begin by defining whether AC, DC, or combination testing is required. AC hipot testers are preferred for insulation verification in dynamic applications, while DC testers are ideal for identifying micro-leakages and dielectric degradation over time.
Next, evaluate the instrument’s test voltage range and current sensitivity, ensuring it aligns with the insulation rating of your devices. Look for models with adjustable ramp rates, programmable sequence tests, interlock functions, and emergency stop features to maintain operator safety. Automatic discharge systems are also essential for energizing capacitive loads safely between tests.
Power electronics manufacturers should consider testers capable of monitoring arc detection and breakdown analysis for more detailed fault characterization. Integrated data logging, USB output, and LAN control enhance traceability and compliance audit trails.
