WebThe study on the existing 132 kV transmission line system further analysed these issues and proposed an appropriate technique for uprating to a 275 kV transmission line system. Finally, the results indicate that the voltage uprating of the 132 kV transmission line system to 275 kV is able to satisfy the electrical clearance requirement envelope. WebOct 14, 2024 · Substation & Transmission Line Voltage Uprating Voltage uprating involves increasing the operating voltage while maintaining the original insulation level. Conversion of existing transmission lines and substations to higher voltages becomes much more practical with application of line arresters.
