Iris Power Stator Slot Couplers (SSCs) are by far the most sensitive partial discharge sensor in the world since they are installed directly underneath the wedges in high voltage stator slots. Partial Discharge Monitoring - Iris Power Iris power provides the partial discharge sensors (epoxy mica capacitor or stator slot coupler), monitoring instrument and diagnostic software to monitor partial discharges and understand the true condition of the insulation.

The different arrival times similarly permit a determination of the location of partial discharge in power cables and gas-insulated switchgear. Previously the preferred instrument for observing the pulses detected by a stator slot coupler was a 1 GHz sample rate or faster, dual channel oscilloscope.
