12 Conductor Ampacity Calculations Date:02/04/2016 Page 3 of Conductor Ampacity Study 115kV 345kV Utilizing the IEEE Steady State Conductor Temperature calculator in PLS CADD, UC Synergetic (UCS) determined that, at a maximum current of Amps, and assuming an ambient temperature of 95 F, 2ft/s wind speed, and maximum solar heating, the resulting conductor temperature is 167 F, which is less than the specified maximum operating temperature of 175 F for 1272 ACSR Bittern (See Attachment A Calculation of Thermal Rating Conductor Temperature). Therefore, 1272 ACSR Bittern will have sufficient ampacity for the project. Utilizing the IEEE Steady State Conductor Temperature calculator in PLS CADD, UC Synergetic (UCS) determined that, at a maximum current of 524 Amps, and assuming an ambient temperature of 95 F, 2ft/s wind speed, and maximum solar heating, the resulting conductor temperature is 122F, which is less than the maximum operating temperature of 135 F for 795 ACSR Drake (See Attachment A Calculation of Thermal Rating Conductor Temperature).
