온라인 부분방전 측정을 위한 Epoxy Mica Capacitor 센서입니다.

Iris Power EMCs are permanently installed (minimum one per phase) as close as possible to the stator winding to be monitored to maximize sensitivity. In order to improve noise separation, the Iris Power EMCs are installed directionally or differentially, depending on the equipment.
Iris Power’s 80 pF EMCs are designed to block the 50/60 Hz power frequency and allow only high frequency (>40MHz) signalsto pass through, be collected and analyzed by an appropriateIris Power portable instrument or continuous monitor.
PD monitoring is applicable to diverse equipment installations. That is why Qualitrol-Iris Power offers four different voltage rated EMCs – 6.9 kV, 16 kV, 25 kV and 28 kV. The choice of which couplers to install is dependent on the operating voltage of the equipment.

The EMCs meet all the reliability requirements in IEC TS 60034-27-2 and IEEE 1434 for PD sensors.
