Generator Users Group

The negative impact of moisture on electrical equipment has been a serious concern since the beginning of the industry. Most senior plant personnel have had experiences with low insulation resistance (IR) and low polarization index (PI) values that have extended an outage. One example provided by subject-matter experts Neil Kilpatrick, GenMet LLC, and James Michalec, […]

If you are not a generator specialist, the things you probably need to know about stator wedges are that they hold the stator bars in the iron, there are lots of them (1200-1800), and they can loosen from age or unusual or persistent vibrations, which interrupts electrical contact, leading to spark erosion. Testing them for
