Most of breakdowns in electric power system are caused by lightning to the tower for high voltage transmission wires. To avoid accidents due to the lightning, it is desired to develop a measurement system for the spatial electric field distribution around the tower. We have developed a new system that can measure the electric field around the steel tower of electric power transmission by using an optical electric sensor. In conventional methods, the sensor is generally illuminated by the light transmitting by optical fibers. On the other hand, the new measurement system illuminates the pockels sensor directly by using a laser to measure the far electric field. Furthermore, our newly proposed feed back system makes it possible to measure the spatial electric field without concerning the change of pockels sensors operation point influenced by temperature change. This system is applicable as a remote sensing system to moniter the spatial electric field around High Voltage Transmission Line.
