On Tuesday, Larry Serbousek, PE, of Innovative Electrical Technology of Texas presented a super program on UPS Configurations and Electrical System Reliability. Larry surveyed the various configurations of medium capacity (223-750 kVA) systems including forward transfer, reverse transfer, isolated redundant, parallel redundant, wireless parallel, parallel "hot sync" redundant, distributed redundant, hot bus tie, and ring bus systems. Larry also discussed issues regarding redundancy and how to achieve higher reliability in this new environment.

We really appreciate Larry taking time from his difficult week to provide us with this presentation. Thank you.
