Transformer Insulation Components – Moulded Components
- Yoke collars Inner and outer are moulded from Elboard LD sheets
- Used for insulation and screening between the winding and the core
- Partly also used for guiding the oil flow.
- Moulded Outer and Inner collars available in segments with 100mm overlap, and also available in full rings.
- These components are made available to order

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.
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.
