JCQ-485 (Type E) Surge Arrester Discharge Counter
——Precision Monitoring for Grid Safety

Product Overview

The JCQ-485 (Type E) Surge Arrester Discharge Counter is a critical device for safeguarding power systems against overvoltage risks. Designed to monitor surge arresters in real time, it records discharge activity and leakage current data, enabling users to analyze lightning patterns and optimize lightning protection strategies. Built with industrial-grade durability, its high-sealing structure withstands harsh environments, making it an essential tool for enhancing the reliability of power transmission and distribution systems.

Key Features

✅ Dual Monitoring: Tracks discharge counts and full leakage current simultaneously to assess arrester health.
✅ Lightning Activity Analysis: Statistical data supports grid lightning protection optimization and fault prediction.
✅ Safety Integration: Connected in series with the arrester grounding circuit, it actively contributes to overvoltage protection.

Core Advantages

1. Military-Grade Protection

o Cast Aluminum Alloy Housing: High-strength, corrosion-resistant, and electromagnetic-shielded for durability in extreme conditions.

o IP68 Rating: Fully sealed against water, dust, and humidity, ideal for outdoor installations.

o Wide Temperature Range: Operates reliably from  -58°F to +185°F (-50℃ to +85℃), suitable for polar or desert environments.

2. User-Centric Design

o Clear Visibility: Large front glass window displays mechanical counters and current indicators for at-a-glance monitoring.

o Quick Installation: Pre-drilled holes with M10×35 bolts enable fast deployment near arrester bases.

o Global Compatibility: Supports 50Hz/60Hz grid frequencies for worldwide applications.

3. Long-Term Reliability

o Anti-Vibration Construction: Internally reinforced components prevent data errors caused by mechanical shocks.

o Maintenance-Free: Precision sealing and robust materials minimize lifecycle costs.
