Thus it is no surprise that stator winding temperature monitoring is widely used on stators rated 3.3 kV and above. RTDs and thermocouples have long been employed to measure the temperature of the winding insulation in the stator slot. Partial Discharge Testing: A Progress Report PD – A Comparison… Figure 3. Off-line PD test on a stator winding measured in the LF (top) and VHF (bottom) frequency ranges. The vertical scale is the apparent pulse magnitude in either nC or mV.

The Iris Power TGA-B system can also be applied to monitor the partial discharges in switchgear and dry-type transformers. Iris Power BusTrac TM - tectra.hu The Iris Power BusTrac System consists of permanently installed capacitive couplers (2 per phase), a dedicated Iris Power BusTrac instrument, a system controller, plus digital communication to continuously monitor stator winding partial discharge (PD) activity. Facilities that have existing bus coupler installations can easily install the Iris ... Iris Power BusTracIITM - Unitronics Electric Iris Power BusTracII OPTIONS Remote I/O over Ethernet with up to 8 analog inputs proportional to operating conditions such as stator winding temperature, voltage, current, or power.
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.
