Study of Current Instability Testing in Andongan In 150 Kva High Voltage Air Line

Air transmission lines generally use ACSR type conductors. As the demand for electrical energy increases, effort to increase capacity of line is carried out by optimizing current-carrying existing line, but problem that arises in this optimization voltage and slope conductor. This study aims determine effect current instability on conductor temperature, slope, angle voltage, which then useful construction structures accordance with mechanical properties conductors used. uses calculation heat balance equation. calculate temperature. The Basic Span Length method used equivalent span length
