This article describes the development of an electronic device for monitoring the condition of a gapless Metal Oxide Surge Arrester (MOSA). The device is equipped with a communication system to convey measurement information to authorized personnel for interpretation, enabling the online monitoring of the surge arrester.
This article presents the development of the theoretical background and the design of an electronic device for monitoring the condition of a gapless Metal Oxide Surge Arrester (MOSA). The device is intended to be used online. Because of the inaccessibility and possible remote location of most surge arresters, it is equipped with a communication system, allowing for the device to convey the measurement of the surge arrester characteristics under any conditions. It is possible to determine the condition of the MOSA by gathering measurements of the surge arrester's resistive component of leakage current. The leakage current information is sent via data transfer unit to a server and, after interpretation, will be forwarded to the authorised personnel through the surge arrester control centre.
