Intelligent Lightning Protection Monitor
Lightning strike is one of the primary threats to the safe operation of power grids. Because distribution networks typically have low insulation levels and lack lightning protection wires, they are especially vulnerable to lightning strikes. Currently, lightning arresters are the main protective devices used across distribution lines and transformers. However, in regions with frequent lightning activity, arrester failure rate remains high. The vast number and wide geographic spread of these devices create significant manpower and financial burdens for outage maintenance and fault troubleshooting. To address this challenge, we have developed an IoT–based monitoring system that continuously evaluates the operating condition of lightning arresters.
The monitoring unit features a passive wireless design (no external power supply, wireless transmission), ensuring low power consumption and seamless deployment. It integrates GPS positioning and provides comprehensive monitoring of lightning current parameters, including peak value, effective value, wave front, duration, energy, frequency, and related metrics. By synchronously detecting time, environmental conditions, and electrical parameters of the arrester, and applying big data analytics with neural network algorithms, the system effectively eliminates interference from factors such as pollution, temperature, humidity, and interphase capacitance. Combined with compliance to multiple international and industry standards—including Qrs, impact times, and leakage current—the system delivers accurate assessment of arrester operating conditions, enabling predictive maintenance and precise fault alarms for efficient operation.
