FFProbe – Rotor Flux Monitoring

Rotor Magnetic Flux Sensor for Greater Than 50mm Air Gap

Product Overview

The Folding Flux Probe (FFProbe) is used for detection of shorted rotor windings in generators and synchronous motors where the air gap exceeds 50mm by measuring air gap flux.

Works with the Following Assets
Assists with the Following Type of Monitoring

The Iris Power Folding Flux Probe (FFProbe) is a non-metallic sensor that detects the magnetic field emanated from each rotor pole in generators and synchronous motors to determine the presence and severity of failure mechanisms including out of round rotor, off center rotor, thermal imbalance of rotor poles, loose poles, stator Migration or shorted rotor turns.

These failure mechanisms can lead to decreased generator power, higher electrical losses, inability to meet the machine MVA rating, significant vibration and catastrophic ground faults.
