Contact UsCapacitor Leakage Tester: What Is It and How It Works?
For the modern capacitor, we used the leakage tester to apply approximately 400 volts, and the leakage was around 25 microamps. That''s a small leakage, so the modern capacitor passed the test. On the other hand, we applied the same 400 volts to the old-fashioned capacitor, and we found it passing through 10x the current.
