A percentage sag test is a method used to evaluate the performance of overhead power lines and their conductors. It involves measuring the vertical sag of a conductor between two support points, typically expressed as a percentage of the span length. This test helps assess the thermal and mechanical properties of the conductor under specific loading conditions, ensuring safety and efficiency in electrical transmission. It is crucial for maintaining appropriate clearances and avoiding issues like excessive sag or conductor fatigue.
