QUALITROL-IRIS POWER IS THE WORLD'S LARGEST PROVIDER OF MONITORING AND FO AVER TESTING EQUIPMENT FOR MOTOR AND GENERATOR WINDINGS A QUALITROL. Company Iris Power HydroTracII™ Continuous On-Line Partial Discharge Monitoring for Hydro Generators Defining Reliability IRIS POWER ON-LINE PRODUCTS

IRIS POWER HydroTracII IRIS POWER HydroTracII SYSTEM 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...

IRIS POWER HydroTracII Features BENEFITS OF CONTINUOUS MONITORING • Sophisticated monitoring and analysis system prevents false indications by digitally separating partial discharges from electrical noise, on a pulseby-pulse basis. • Proven filtering and pattern recognition enhances noise separation, allowing for a reliable and objective detection of stator winding problems such as poor impregnation, overheated windings, coil movement in the slot, ineffective or deteriorating grading/ semiconductive material problems, and contamination. Couplers installed on a hydro generator stator • The system’s...

IRIS POWER HydroTracII Options - Remote I/O over Ethernet CONNECTION WHAT IS PARTIAL DISCHARGE? • Remote inputs with up to 8 analog points proportional to operating conditions such as stator winding temperature, voltage, current, or power. These conditions are recorded for trending and analysis. Pulse Count Rate [pps] (log) • Remote outputs with 6 analog outputs proportional to the level of PD activity (+Qm and –Qm) of the machine couplers. This is applicable in situations where the user is interested in having the real-time PD activity from their machine acquired by their DCS or control system....
