IS successfully completed a 235 KV capacitor bank upgrade projects for Western Area Power Administration (WAPA)


WAPA in the state of Arizona provided IS with a very challenging and interesting project. WAPA has two capacitor banks located in Arizona which had a serious failure preventing operation of both banks. Scope of this upgrades project includes:


  • Initiated the engineering walk dow

  • Scavenged documentation and deciphered the rest

  • Mobilized a prep team to identify and label the entire system that was to be modified

  • Design teams worked in tandem designing the new system and developing conversion plans while the other team developed the PLC code.

  • Engineered a new protocol to interface new to old.

  • Performed multiple layers of testing at ISI facilities and then invited WAPA team to witness the testing.

  • Performed system installation

  • After successful field commissioning of the new system configuration, both capacitor banks went on line May 30th, 2008 without incident.
