- Sensitive & Reliable Recording: Equipped with high-quality internal components to ensure precise counting even under low-current discharge conditions.
- Clear Visual Display: Features an easy-to-read dial or digital interface, allowing maintenance crews to perform quick visual inspections without specialized equipment.
- Wide Compatibility: Designed to be connected in series with 11kV to 220kV surge arresters or combined over-voltage protectors.
Product Description
The JS/JCQ Series Discharge Counter is a vital diagnostic tool used in conjunction with surge arresters in power generation, transmission, and distribution systems. Its primary function is to monitor the arrester’s health by recording the frequency of over-voltage events it has suppressed. For high-voltage substations (35kV and above), our monitoring devices provide a clear indication of when an arrester has reached its duty cycle limit. This allows for proactive maintenance, preventing unexpected equipment failure and ensuring the continuous reliability of your power network.
