摘要

This paper presents the protection procedures implemented in a power line sensor in order to make it compatible with the electromagnetic environment, especially with the stresses imposed by lightning flashes. The paper includes the sensor description and simulation results of lightning surges coupled to the device through its external interfaces. It is shown that the protection of the radio-frequency circuitry requires the installation of a high-pass filter at the antenna port and that the protection of the voltage-measuring circuit can be accomplished by using a voltage divider combined with a low-pass filter. By its turn, the protection of the current-measuring circuit is achieved by the installation of surge protective components.
