Abstract :
The upgrading of several 69 kV pipe-type cable feeders on the Potomac Electric Power Company (PEPCo) transmission cable system is discussed. The methods used for the ampacity calculation are described. The fluid circulation approach required to meet the feeder emergency load requirements are discussed. For the feeders that were in service for approximately 40 years, a system life evaluation was performed
