    Continuous Online Partial Discharge Monitors

    The BusTrac™ and HydroTrac™ monitors are the latest in continuous on-line monitoring of PD activity in generator stator windings. They use unique methods of noise separation employing at least 2 capacitive couplers per phase. This ensures reliable and repeatable measurements by minimizing the risk of false alarms. The test data can be easily interpreted by a maintenance professional that participates in a one-day training seminar, offered by our PD experts. Since the instrument is fully compatible with all previous generations of the Hydro, Turbo or Motor coupler technology, maintenance personnel can use the historical data to make a seamless comparison to similar machines, and they can continue to solicit access to the growing Iris database of over 60,000 test results.

    PDTrac™ Monitor

    The PDTrac™ instrument provides automated, continuous partial discharge (PD) measurements for motors, generators, switchgear and dry-type transformers using one capacitive coupler per phase. The PDTrac™ monitor provides maintenance professionals with an opportunity to continuously monitor equipment for insulation deterioration. This instrument will automate measurements and store recorded data for up to 2 years. The PDTrac™ partial discharge monitor options include Sensor Input Modules, Analog Signal Output Module and dry contact Alarm Outputs. The PDTrac™ instrument can be completely controlled from a remote location and contains advanced communication options including RS485 or Ethernet TCP/IP. Plant personnel easily configure it, tests your machines, and receive an alarm when a problem is detected, all from your office!

    Guard System

    The HydroGuard™, BusGuard™, and TurboGuard™ products collectively referred to as Guard systems, can be programmed to continuously measure partial discharge (PD) activity on motors and generators rated 6kV and above. The system is sensitive to the most common stator winding failure mechanisms such as over heating, contamination and loose windings. This allows plant personnel to plan corrective action if the Guard detects problems. The Guard line is the premium continuous monitoring system since it also provides PD data as a function of AC phase angle.

    Rotor Winding Monitoring

    CSMeter™ Detector

    CSMeter™ instrument is a battery powered, hand-held data acquisition instrument which provides on-the-spot diagnosis of broken rotor bars
    for a wide range of induction motors. The CSMeter™ instrument applies advanced algorithms to specifically guard against false indications and consequent misdiagnosis in healthy motors. Additional software modules allow the user to extend diagnostic capabilities to include, for example, air gap eccentricity.

    FluxTrac™ Monitor

    The FluxTrac™ monitor is a sophisticated on-line monitor for remotely acquiring magnetic flux data from air gap mounted flux probes in synchronous motor and generator rotors. Air gap flux monitoring is a proven tool used to provide information on the integrity of the rotor winding inter-turn insulation. This information is critical in planning maintenance, explaining abnormal vibrations, and verifying new and rewound rotor integrity.

The TGA-B™ instrument determines the magnitudes, rates and polarities of voltage pulses created by partial discharges. Additional parameters such as NQNs and peak pulse magnitudes are also calculated. The instrument comes equipped with user selectable USB or LAN communication modes. An external computer is used to acquire, display, and store PD test results quickly and conveniently.

    Partial Discharge Sensors

    Hydro/Turbo/Motor Couplers

    Epoxy Mica Capacitors (EMCs) couplers detect stator winding PD activity and separate unwanted electrical noise. Three couplers are typically
    needed for motors, whereas 6 couplers are typically used on generators. A standard package includes 3 to 6 couplers, mounting hardware, insulating tapes, termination box, and coaxial cables.

    Stator Slot Couplers

    IRIS’ stator slot couplers (SSCs) are specifically designed to detect stator winding partial discharge activity in operating gas or steam turbine generators. Used in conjunction with IRIS’ TGA-S™ test instrument, the SSCs are permanently installed under the stator winding wedges in existing machines, or between the top and bottom bars in new or rewound machines.

  • DC Ramp Test Set


    The DCR 50 is a simple off-line DC test to identify problems in the stator groundwall insulation system of large AC electric machines before an unexpected in-service failure occurs. Unlike the pass or fail of a DC or AC hi-pot test, the DC ramp test gives diagnostic information and can be stopped before a failure occurs.

    Unlike a stepped voltage, the ramped voltage enables the user to separate the polarization and capacitive current components from the leakage current so that small insulation defects can be easily found.

    A single-phase test usually takes less than an hour to perform and can be done by one person. The DCR 50 tests according to IEEE Std 95-2002.

    The DC Ramp Test method has been proven in use (for almost 40 years) by the US Bureau of Reclamation and others on a wide variety of machines with asphalt, polyester and epoxy-mica insulations.

    Test curves are captured on a PC to allow easy comparison to similar machines or past results.

  • Epoxy Mica Capacitators

    Epoxy Mica Capacitors (80 pF)

    Partial Discharge Sensors for Testing High Voltage Electrical Equipment 

    Iris Power’s durable Epoxy Mica Capacitors (EMCs) are designed to detect Partial Discharge (PD) activity in electrical equipment (AC motors, generators, switchgear and dry-type transformers) while not imposing on the machines operation or reliability in any way.

    EMCs are permanently installed (minimum one per phase) as close as possible to the equipment to be monitored to maximize sensitivity. In order to improve noise separation, the EMCs are installed directionally or differentially, depending on the equipment.

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

    PD monitoring is applicable to diverse equipment installations. That is why Iris Power offers four different voltage-rated capacitive couplers – 6.9kV, 16kV, 25kV and 28kV– the choice of which to install is dependent on the operating voltage of equipment.
