Tennessee Valley Authority installs system to monitor large transformers

Minneapolis, MN, Oct. 31, 2003 -- Cannon Technologies Inc. announced that it has commissioned its Substation Advisor System at TVA's Cordova Substation near Memphis, Tenn.

The Advisor System is being used to monitor 400 MVA, 500 KV autotransformers. The system incorporates combustible gas and other transformer operating information gathered from GE Hydran, Morgan Schaffer Calisto, Cannon, and other third party sensors; along with site weather information, in GE Harris D25 data gateways. The entire system was integrated and installed by Cannon.

TVA has also installed Cannon's Yukon™ eSubstation transformer monitoring application at its Chattanooga offices to enable enterprise access to the Advisor System; providing substation alert messages, along with real time and historical data and trends to appropriate TVA personnel. Information is delivered to the Yukon Server via wireless Ethernet from the transformers in the substation to the TVA Wide Area Network.

eSubstation is a module of Cannon's Yukon software platform for optimizing energy delivery and managing critical assets. Other Yukon modules include direct load management, load curtailment, load aggregation, control of distributed generation, AMR, and centralized capacitor control. Yukon functionality is offered as both an Internet based service running on Cannon servers, or as a licensed installation in the utility data center.

Cannon Technologies, Inc. is a privately held company founded in 1987 specializing in the development of software and hardware systems for electric utility automation including load management, substation information systems, capacitor control, and remote metering. Cannon's user base exceeds 300 electric utilities. The company is based in Golden Valley (Minneapolis), Minnesota, with other locations in Iowa, North Dakota, Nebraska, Virginia, Colorado and Texas.
