Over Head Transmission Line Controlled Switching
Controlled switching is an advanced power system technique used in overhead transmission lines to precisely operate circuit breakers at the optimal point on the voltage or current waveform. This minimizes switching transients, reduces electrical stress on equipment, improves system reliability, and extends the service life of transmission line components, transformers, and switching devices. The technology is widely applied in high-voltage and extra-high-voltage networks to enhance power system stability and operational performance.
