Description

Surge Arrester Monitor Calibrator

Model: XHJS401A | For 1000kV-Class DC Arrester Monitors
Product Overview

The XHJS401A surge arrester monitor calibrator is an independently developed precision test instrument designed to meet the calibration needs of DC surge arrester monitors used in power systems, such as Model JCQ(WZ)-16. It is mainly used for the calibration of 1000kV-class arrester monitors, delivering stable measured values, strong anti-interference heterodyne output in online state, standard sine wave output and a built-in battery for convenient on-site measurement. It provides a complete solution for verifying the operating status of surge arrester leakage current monitors, action counters and their associated alarm circuits.

Applications & Target Audience: Engineered for UHV/EHV transmission line operation and maintenance units, electric power research institutes and metrology & testing organizations, surge arrester and insulator manufacturer quality control departments, substation automation system integrators and power transmission & transformation commissioning companies that need to calibrate 1000kV-class DC surge arrester monitors and verify their action counters and leakage current readings.
