Overview

With advanced hierarchical and distributed structure, the HNPBL-1000 lightning arrester online monitoring system adopts the bus control technology and modular design principle to greatly improve anti-interference performance, measurement accuracy and stability of the system, meeting the practical requirements on the industrial site, and adopts expert diagnosis system for scientific analysis and diagnosis of the data acquired so as to understand and master the health status of the power transformation equipment in a timely and convenient manner.

Through real-time monitoring of full current, resistive current, capacitive current and number and moment of lightning strokes of the lightening arrester, and analysis and fitting treatment of the data monitored, and in combination with the onsite work condition, it is possible to timely discover problems such as increased insulator leakage current or insulating bar leakage current of the lightening arrester caused by dirt or interior damping so as to avoid occurrence of accidents.

Main Features

• With high-precision active zero flux straight-through current transformer, automatic selection of amplification factor according to the current measured to achieve high-precision measurement

• Dynamic phasor compensation algorithm to achieve high-precision measurement signal analysis

• Digital filtering algorithm to eliminate the “zero drift problem” caused by the analog filter

• Distributed measurement structure, i.e. in-situ measurement and digital transmission

• The system can be installed when the power is turned on, that is to say, the system can be connected conveniently and quickly with no need to power off the main equipment
