The Iris Power HydroTracII system consists of permanently installed capacitive couplers, minimum of 2 per phase, a dedicated Iris Power HydroTracII monitor, plus digital communications for configuring the monitor and downloading the stored PD data. The system is an economical means of providing automated, continuous partial discharge (PD) measurement and trending.
Plants that have previous PDA coupler installations can install the Iris Power HydroTracII monitor by connecting the monitor to the existing coupler termination box. This does not require an outage, and the installation effort is limited to providing power to the monitor, connecting the alarm output, and running a communications link to a local control room computerif remote configuration and downloading of data is desired.
