Xi'an Shendian is the earliest manufacturer to develop monitoring recorder without residual voltage, which was granted national patent (Patent No.: 200820221702.2). Discharge recorder is equipped with the high-performance microprocessor as the central intelligent instrument and the inductive signal collector without residual voltage, which will not increase the residual voltage of surge arrester.
The monitoring recorder can monitor the number of actions and the leakage current of surge arrester, and give an alarm for leakage current beyond the limit to remind the user to detect the arrester.
According to the demands of the customers, it can also be set with RS485 communication interface to transmit, save, edit or print the information and data stored in the host computer, realizing remote monitoring and meeting the requirements of unattended operation.
Featured by stable operation, the monitoring recorder has been widely used in the electric power systems of electric power, wind power, photovoltaic power generation, metallurgy, coal, petrochemical engineering and other industries.
