Resistive current energized monitoring system for metal oxide arrester (MOA) based on compass synchronous time service

The invention relates to a resistive current energized monitoring system for a metal oxide arrester (MOA) based on compass synchronous time service. The system comprises a constant voltage transformer (CVT) on-line detection terminal, an MOA handheld detection terminal and an upper computer, wherein the CVT on-line detection terminal is arranged at an on-site CVT; the MOA handheld detection terminal is connected to two ends of a lightning-stroke counter which is connected in series to the lower end of the MOA; the CVT on-line detection terminal is in wireless communication connection with the MOA handheld detection terminal; and the MOA handheld detection terminal is connected with the upper computer. Compared with the prior art, the resistive current energized monitoring system for the MOA based on the compass synchronous time service has the advantages of accurate and comprehensive measurement data, simplicity in wiring, low cost and the like.
