The use of extra-high voltage lines can increase efficiency and reduce voltage drop but cause corona generation. Corona that occurs increases channeling losses and causes disruption to the environment in the form of Audible Noise (AN) and Radio Interference (RI). Audible Noise (AN) and Radio Interference (RI) that are too large will disturb the community around the transmission line. The use of a bundle conductor is a way to reduce the risk of corona. This paper discusses the effect of variations in the bundle conductor on noise interference and radio interference in 275kV extra-high-voltage air lines (SUTET). The types of variations include variations in the number of beams, variations in the distance between sub-conductors, and variations in diameter of the conductor. Next, the Audible Noise (AN) and Radio interference (RI) values are calculated for the Latuppa (Palopo) - Pomana channel planning. The results of the calculation of AN and RI values on SUTET 275kV are still included as safe criteria because the value is still below the criteria limits of Perry and SPLN 46-1-1981 concerning the Noise Level Limitation Guidelines and the IEEE Radio Noise Design Guide about the maximum limit of RI.

Peak load on Berawa Feeder is very high exceeding the maximum limit set by PLN which causes Losses and high voltage drop values, so reconfiguration of Repeater via LBS Canggu Club and LBS Damai Residance is carried out, using 3 distribution points. The flow before being reconfigured in the Swamp Feeder was 242A to 180.2A, while the previous Bumbak Feeder was 82A to 144.7A. losses previous deliveries of Bumbak Feederwere 5.2kW to 22.15kW, while previous Berawa Berulang was 117.1kW to 55.11kW, drop the previous Bumbak Feeder voltagewas 102kVA to 24kVA, whereas the previous Swamp Feeder was 775.4kVA to 490.2kVA. Load surges and decreases are caused by changes in load and channel length after being reconfigured.
