2.8 Small Wind Turbine Lightning Current Monitor

Product Overview

The HD-LC-RS485/CQS small wind turbine lightning current monitor is a new product independently developed by our company for online lightning current monitoring of wind turbine generators. Featuring multi-channel synchronous acquisition and multi-parameter comprehensive measurement, it can monitor key lightning data in real time, including lightning current peak value Ip, charge quantity Q, specific energy W/R, lightning current steepness K, lightning polarity, strike time and sensor status. It can continuously store multiple lightning event records for user statistical analysis, providing critical data support for lightning protection design optimization and lightning accident analysis of wind turbines.

Adopting a highly integrated design, the device is compact and small in size. Its miniaturized form allows direct installation inside existing electrical cabinets or control cabinets of wind turbines, without extra space or cabinet modification. It enables flexible and efficient deployment and simplifies installation and maintenance.

The product is equipped with two independent RS485 interfaces: one supports the Modbus RTU communication protocol, and the other supports the Profibus DP communication protocol, compatible with mainstream industrial fieldbus standards. Users can perform secondary development based on the provided communication protocols for seamless integration into the existing wind turbine monitoring system, realizing multi-point online monitoring and centralized management across wind farms.
