TRANSMISSION LINE SAG MEASUREMENT METHOD CAPABLE OF MINIMIZING A MEASUREMENT ERROR

摘要

PURPOSE: A transmission line sag measurement method is provided to accurately measure the current sag of a power line about an iron tower and easily construct the design sag of a power line.;CONSTITUTION: A measuring apparatus is installed in a spot where an electric line support point of both sides pylon is seen(ST1). The measuring apparatus is installed in one electric line support point among the pylons(ST2). The measuring apparatus transmits collimation value data to a PDA(ST3), wirelessly or using a cable. The measuring apparatus collimates about the electric wire support point of a different pylon(ST4). The PDA calculates the location of the horizontal angle of a sag reference line and displays it(ST6). The PDA displays the sag value(ST7).;COPYRIGHT KIPO 2010
