Online monitoring device for cable sheath grounding circulating current

Introduction: Safeguard Cable Safety and Enhance Power Grid Reliability

In the modern power transmission system, high-voltage cables are key carriers for power delivery, and their safe and stable operation is directly related to the reliability of the power grid and power supply quality. However, abnormal ground current in cable sheaths is one of the common hidden faults. If not monitored and dealt with in a timely manner, it may lead to local overheating of cables, accelerated insulation aging, and even serious consequences such as short circuits and power outages, affecting social production and residents' lives.

To address this industry pain point, Teluck Technology has launched the TLKS-PLGDCable Sheath Grounding Current Monitoring Device. Relying on advanced technology, intelligent algorithms and reliable performance, it realizes all-weather precise monitoring and early warning of cable grounding current, providing solid guarantee for the safe and stable operation of the power system.

I. Innovative Working Mechanism: Intelligent Monitoring, Precise Early Warning

TLKS-PLGDCable Sheath Grounding Current Monitoring Device adopts an integrated intelligent monitoring architecture, and realizes all-round monitoring of cable grounding current through the following processes:

1. Data Collection: Adopts high-precision clamp-type current sensors, which surround the cable sheath grounding wire to collect grounding current data in real time.
2. Signal Processing: The collection terminal converts analog signals into digital signals and stores them locally.
3. Remote Transmission: Uploads data to the background monitoring system in real time via 2G/3G/4G network.
4. Intelligent Analysis: The system has built-in intelligent algorithms to conduct in-depth analysis of historical and real-time data, identifying abnormal fluctuations and over-threshold situations.
5. Timely Early Warning: Once abnormal current is detected, the alarm mechanism is triggered immediately to notify operation and maintenance personnel to investigate in time and prevent problems before they happen.

II. Excellent Technical Parameters: High Precision, High Reliability
