Hydrogen Cooled Generator Upgrades

August 29, 2018

The first hydrogen cooled generator was put into service by GE in 1937. Many of the design features of those early generators still persist today. TRI Transmission and Bearing Corp. has successfully implemented many upgrades to these old generators.

I was invited to present the benefits of generator upgrades at the most recent EPRI User’s Group meeting in Baltimore. The video here discusses the key points of that presentation.

When shafts rub

July 12, 2017

It is undesirable to have a shaft to rub metal to metal with another machine components…but it happens. When it does, the question often asked is “Can the shaft be fixed?” It is easy enough to bring in an service that does field machining to fix the surface of the shaft, but the heat caused by a rub alters the shaft steel much like the heat affected zone that occurs during welding.

This video explains what happens with crystalline structures in steel when exposed to intense heat.

Below is a photo for a part that rubbed. Over 0.1″ has already been machined away and you can see the hard spot that still remains.Vaneplate-hardspot
