Capacitor Testing
The test system includes control of the nominal AC supply via an integrated variac and also the stress impulse that is applied to the capacitors. Impulse amplitudes are programmable up to 8kV which covers all the requirements. X1 capacitors are stressed up to 4kV, X2 and Y4 capacitors up to 2.5kV and Y2 capacitors up to 5kV. Capacitors up to 1F can be tested with the COMP0804CAP and up to 50F when the COMP0804CAP includes also the decoupling elements to prevent the disturbance signal entering the power mains supply. Control is from the EMC PARTNER Operating System (EPOS) interface which allows fast and easy control of the test process.
