A coupling capacitor (C C) is a very common coupling method when performing a PD measurement as described in the IEC 60270 standard. When a partial discharge event occurs, the coupling capacitor provides the devices under test (DUT) with a displacement current, which is measurable at the coupling devices (CPL).
When a partial discharge event occurs, the coupling capacitor provides the devices under test (DUT) with a displacement current, which is measurable at the coupling devices (CPL). Such an approach provides additional information about the test discharge (PRPD) measurement. OMICRON ofers standard coupling capacitors from 12 kV up to 100 kV.
discharge (PRPD) measurement. OMICRON ofers standard coupling capacitors from 12 kV up to 100 kV. When using a coupling capacitor without an integrated measuring impedance, the low side of the coupling capacitor has to be connected to the input of the CPL measuring impedance (basic test setup with measurement on ground potential).
