New Technology to Evaluate Performance of Sub-transmission Power Lines to Help Prioritize Upgrades ย
COLLINSVILLE – Ameren Illinois is using groundbreaking technology to more quickly and accurately determine when sub-transmission power lines should be upgraded, improving service reliability and saving customers money. A device known as "LineVue" is placed on the sub-transmission power lines to assess the steel core of wires – aluminum conductor steel reinforced or aluminum core steel supported – to identify any potential defects, such as frays in the line, and determine the optimal time to replace them. The unit is controlled remotely from the ground. Sub-transmission lines typically transmit 34.5 kilovolts to 69 kilovolts of electricity to regional distributions substations before the voltage is stepped down further to be delivered to customer homes and businesses. More than 45,000 miles of sub-transmission and distribution power lines span the Ameren Illinois service territory. Approximately 1.3 million utility poles, including 2,000 high-strength composite
