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.

Past Tech Notes

September 1, 2016

Since 1994, Dr. Mel’s Tech Notes have been issued from time to time. The Tech Note has evolved.  Since 2004, they have been distributed through email.  Prior to email, the Tech Note as sent out by fax.  When we first started sending out Tech Notes, the scope and length of the information was limited by the fax technology.  Most Tech Notes were brief, one page summaries of our latest projects. Now the Tech Note is distributed via email and published on the TRI Web Site (http://www.turboresearch.com/); the length and scope of the Tech Notes are no longer hampered by the delivery method.    Read the rest of this entry ?
