Application of GPS for Sag Measurement of Overhead Power Transmission Line
نویسندگان
چکیده
Overhead conductor sag may be measured by different methods. In the paper measurement of sag of 66KV power transmission line under shut down conditions at no wind load using standard handheld GPS receiver BT 359 has done. The real time direct measurement of overhead conductor sag is needed for the operation of power transmission system. The measurement of conductor tension, temperature and ambient weather conditions are not required to monitor in this method. The digital signal processing (DSP) techniques is used to get better accuracy of GPS measurements. The Least Square Parameter Estimation (LSPE) method for the error estimation of GPS measurements is also incorporated.

متن کاملOverhead Transmission Line Sag Estimation Using a Simple Optomechanical System with Chirped Fiber Bragg Gratings. Part 1: Preliminary Measurements
A method of measuring the power line wire sag using optical sensors that are insensitive to high electromagnetic fields was proposed. The advantage of this technique is that it is a non-invasive measurement of power line wire elongation using a unique optomechanical system. The proposed method replaces the sag of the power line wire with an extension of the control sample and then an expansion ...
