Product specifications: XSN-R-LA
Product Introduction:
Xsn-r-la capacitive equipment and lightning arrester online monitoring system adopts bus control technology, which is composed of two parts: the measurement monitoring system installed in the substation and the intelligent unit installed in the operation site. Through the public telephone network, the monitoring data of several substation monitoring systems can be collected to the upper data management and diagnosis system. Realize on - line monitoring of high voltage equipment insulation in multiple substations.
