TF Probe ™
Iris power’s TF Probe™ (Total Flux is specifically designed to measure the total air gap flux and detect shorted turns in salient pole motors, hydro generators, and in turbine generators. The probe when connected to the portable RFA-II™ instrument, allows the user to monitor the health of the generator field winding on-line, and continuously.
The TF Probe is a small, flexible, printed circuit board which is affixed to a stator tooth with epoxy – no drilling or wedges, or fragile components intruding into the air-gap. In many machine designs, it is even possible to install the probe without removing the rotor – a definite advantage in retro-fit applications.
An optional hermetically sealed single penetration feed through is available for hydrogen cooled machines.

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.
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!
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™ 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.
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.
Perioric Partial Disscharge Monitoring
The TGA-S™ portable instrument is designed to monitor PD in turbo generators equipped with Stator Slot Couplers (SSCs). The
TGA-S™ 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.
The PDA-IV™ portable instrument is specifically designed to monitor PD in hydrogenerators equipped with PDA capacitive couplers. The PDA-IV™ 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.
The TGA-B™ portable instrument is designed to monitor PD in motors and turbine generators equipped with Bus capacitive couplers. 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
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.
