QUALITROL – PD Monitoring System

The Iris Power PDTracII is a continuous online partial discharge (PD) monitoring system designed for motors, generators, dry-type transformers, and air-insulated switchgear rated up to 35 kV. It provides automated, reliable PD measurement and trending, helping asset owners detect insulation deterioration early, avoid catastrophic failures, and optimize maintenance planning.

• Continuous Online Monitoring: Automated PD measurement for motors, generators, switchgear, and dry-type transformers.
• Superior Noise Separation: Advanced filtering and pulse shape analysis reliably distinguish PD from electrical interference, minimizing false alarms.
• Permanently Installed Sensors: Uses proven 80pF Iris Power Epoxy Mica Capacitors (EMC) for each phase.
• Remote Inputs: Supports up to 8 analog points for trending operating conditions (temperature, voltage, current, power).
• Data Analysis: Outputs phase-resolved PD plots, pulse height analysis, and summary numbers (Qm, NQN) for trending and benchmarking.
• Global PD Database: Results can be referenced against Iris Power’s severity tables, based on over 700,000 machine tests.
• Communication: Standalone or networked operation via USB, Ethernet, or Modbus; alert relay output for remote indication.
• Certifications: ATEX/IECEx, C-US Class I Division 2, and other hazardous location certifications.
• Local ambient humidity and temperature sensor
• Configuration for existing low-frequency capacitive couplers (1nF–2nF)
• Multiple enclosure and certification options for hazardous locations
• Integration with plant SCADA systems via Modbus TCP/IP
