Works with the Following Assets
Assists with the Following Type of Monitoring

Iris Power Epoxy Mica Capacitors (EMC) are designed to detect Partial Discharge activity in motors, generators, switchgear and isolated phase bus while not imposing on the machine’s operation or reliability in any way.

Iris Power’s 80 pF EMCs are designed to block the 50/60 Hz power frequency and allow only high frequency (>40MHz) signals to pass through, be collected and analyzed by an appropriate Iris Power portable instrument or continuous monitor.
