138kV Line Upgrade To SEL Relaying

Posted by AMPED I on July 11, 2015
 
Amped I has begun the design of a 138kV line upgrade in Indiana. This line upgrade will improve the electrical grid’s reliability by upgrading outdated, pre-existing protection and control relays with Schweitzer Microprocessor relays and automation controllers. One of the challenges faced in this design was obtaining the technical clarification of design details that match supplied templates to existing schemes. Amped I expects to complete this design in the summer of 2017.
