PPM Corona Probe - Offline Partial Discharge Tester

PPM Corona Probe - Offline Partial Discharge Tester

Product Overview

The Corona Probe is an off-line instrument to accurately pinpoint the source of partial discharge (PD) in a particular slot in generators and motors.


The Iris Power PPM-97 Corona Probe supplements on-line partial discharge measurements by more precisely locating the partial discharge to a particular slot and position, with the motor or generator winding energized by an external high voltage AC source.

This offline test provides a method of testing the quality of bonding between the ground wall insulation layers in the slot sections of new resin-rich and individually VPI’d coils/bars, and the adequacy of slot resin fill in global VPI windings.

On Line/ Off Line Partial Discharge: IRIS TGA

On Line/ Off Line Partial Discharge: IRIS TGA

The test enables predictive maintenance of generators resulting in increased reliability and extension of the service life. The technique, developed by IRIS POWER, was introduced over two decades ago and has since been applied to more than 6,000 windings of generators, and is the most popular method in the world to measure partial discharge (PD). The method is non-destructive and is recommended by the generator manufacturers and the industry standards, such a as IEEE Std.1434-2000

ELCID: IRIS ELCID Evolution

High Pot: Megger 220072- 70 kV DC

Iris Power ELCID Evolution tester operates at only 4% of normal operating Flux, generated by its quickly installed excitation kit. Any imperfections in the core inter/laminar insulation produce fault currents which are detected by a chattock coil and analyzed by the Iris Power ELCID Evolution signal processing unit. Measurement results are digitally stored in the PC for analysis and report generation, and faults can be precisely located in the core. Future results can be compared to past results for trending analysis.

Stator Wedge Tightness: IRIS Stator Wedge Analyzer

Stator Wedge Tightness: IRIS Stator Wedge Analyzer

The Iris Power SWATM instrument allows to easily and effectively assess the tightness of stator wedges in motors or generators. If the wedges are loose, this may allow stator coils or bars to vibrate in the slot, leading to insulation abrasion and a ground fault. Electronic measurement and storage enables easy and accurate trending of wedge tightness data from test to test.

Stator wedges are traditionally tested for tightness by tapping them with a hammer and listening to the sound produced. This method is slow and prone to inconsistency, the Electronic wedge tightness evaluation is faster, more accurate and provides more consistent results. The Iris Power SWA instrument can be used to test most types of generator and motor stator slot wedges, including those with ripple springs

Magnetic Particles

Magnetic Particles

Magnetic particle testing is one of the most widely utilized NDT methods since it is fast and relatively easy to apply and part surface preparation is not as critical as it is for some other methods. This method uses magnetic fields and small magnetic particles to detect flaws in components.
