Company, IRIS Power Engineering, Maughan Engineering Consultants, Ohio Edison, Duke Energy, and Lake Road Generating. The report is a corporate document that should be cited in the literature in the following manner: Generator On-Line Monitoring and Condition Assessment: Partial Discharge and Electromagnetic Interference. EPRI, Palo Alto, CA ... Method and device for distinguishing between partial ... The present invention further provides a device for distinguishing between partial discharge and electrical noise received by a sensor having two outputs for transmitting a signal proportional to an amplitude of a pulse received by the sensor, the sensor being directional such that the location of the pulse relative to the sensor determines the ... How many slots does the stator have? - Quora Stator slots will usually be a multiple of 6. The exception may be slow speed motors which may be a fractional slot configuration. Generally speaking, as the torque rating (horsepower/speed) goes up, the number of stator slots goes up. For a given number of stator slots N1, there are general restrictions on number of rotor slots N2:
• Iris Power TurboGuard system for use with turbo generators equipped with stator slot couplers. The Iris Power Guard system uses Iris Power EMCs (epoxy mica couplers) or Iris Power SSCs (stator slot couplers) that are permanently installed on motors and generators (6kV or higher). Each machine to be monitored requires one Data Acquisition
Couplers - Unitronics Electric Iris Power 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 the Iris Power TGA-S test instrument, the SSCs (shown below) are perma- Iris Power Bus Couplers - SM Systems Iris Power Bus Couplers Typically used for motors and small turbo generators (less than 100 MVA), Bus couplers detect stator winding PD activity and help separate unwanted electrical noise. In the recent years, Epoxy Mica Capacitors (EMCs) became the industry's choice due to sufficient sensitivity and the relative ease of installation. Portable Instrument for Motors and High Speed Turbine ... measuring system uses Iris Power Stator Slot Couplers (SSCs) and the Iris Power TGA-STM instrument. The Iris Power TGA-B system can also be applied to monitor the partial discharges in switchgear and dry-type transformers.
