Surge Arrester Monitoring IED with Modbus/IEC 61850 Support / IP68-Rated Real-Time Lightning Protection for High-Voltage Grid Safety
Surge Arrester Remote Metering Online Monitoring Device
— Intelligent Outdoor Monitoring Expert for High-Voltage Systems
Product Overview
The Surge Arrester Remote Metering Online Monitoring Device is a precision-engineered, all-weather solution designed for real-time monitoring of surge arresters in high-voltage power systems (220kV and below or higher). By continuously tracking full current, discharge counts, and discharge duration, this device delivers critical data for fault prediction and maintenance planning. Featuring an IP68-rated precision cast aluminum enclosure and opto-isolated RS485 communication, it ensures reliable performance in harsh outdoor environments, making it an essential tool for enhancing grid safety and mitigating lightning-related risks.
Core Features
