2018-03-29 15:51


Product Overview

JZJY high-voltage on-line insulation monitoring device is a device that can on-line monitoring high-voltage power cables and insulator insulation status, which is used for diagnostic cable and insulator early defects and accidents hidden danger, control sudden insulation accident, monitoring electrical equipment insulation property good or bad provides effective information, and directly affect the safe and reliable operation of equipment. The device is easy to install, simple to operate, strong in real-time and accurate in monitoring information, and is widely used in 0.4kV~35kV power System.

The device is controlled by a high-performance microprocessor, and LCD display shows the current operating state of the system. When diagnosing the operation equipment failure, the indicator light and alarm relay action, so that equipment maintenance personnel to keep abreast of the cable line and insulator line insulation status. Moreover, the device also has RS485 communication interface to facilitate communication with the host computer.
