Works with the Following Assets

Assists with the Following Type of Monitoring

Offline Testing

Loose stator wedges may lead to vibration and erosion of stator insulation in electric generators and motors that can eventually cause failure.

The SWA can be used to test all types of generators and motor stator wedges to provide a quick and objective measure of the relative tightness of all stator wedges in a machine.

Product Details

Features

The hand-held probe is small, light and adjustable to fit most rotating machines, regardless of slot size or depth.
In Standard test mode, tightness of each wedge is compared to predefined values while in Advanced mode, the tightness of each wedge can be compared to all other wedges in the winding, the wedges of another winding or any user selected external reference.
The diagnostic software provides a permanent record of test data and automated reports with the ability to export test data to spreadsheets, databases, or word processors.

Options

The Iris Power Stator Wedge Analyzer can be equipped on an Iris Power Robotic Inspection Vehicle for automated positioning and testing.
