Amped I has just completed a project that removed the final leased 138kV Audiotone circuit from service replacing the old antiquated electromechanical relays with microprocessor relays that utilize direct fiber and multiplexed relay communications.  As a challenge to the project we designed a 138kV freestanding CT stand to bridge a trough and added as well as replaced CCVT’s for two lines.  We also designed new 138kV Bus relaying to protect the primary bus at the station eliminating old DC interlocking schemes.  By adding bus protection the reliability of the 138kV was significantly increased as well as reducing required zones of protection for outages.  These lines went into service recently completing a program to replace all antiquated leased phone circuits used in relaying on the transmission system.
