AMPED I completed five remote end line upgrades due to the construction of one new substation. The projects consisted of three 345kV line relaying packages and two 138kV line relaying packages. The communication methods consist of Power Line Carrier or fiber depending on the remote end. The SCADA/RTU system was also upgraded/ modified. Relays used include SEL321, SEL 311, SEL 352, SEL 501, RFL 9780, RFL 9785, and SEL 2032. Schemes used were PLC OCB scheme, Fiber current differential, Step Distance and Breaker Failure.


Our services for this power infrastructure project began in Fall 2012 and were completed by early 2013.
