1. Introduction

In the guarantee system for stable power supply of power systems, the performance of grounding resistance is a key link, directly related to the overall safety of the power grid. With the continuous increase in power grid voltage levels and the frequent occurrence of extreme weather, the risk of performance degradation faced by grounding systems has increased significantly. Once the grounding resistance value exceeds the safe range, it is very likely to cause equipment failures and power outages.

The traditional manual detection mode has obvious limitations: not only is the operation process cumbersome and inefficient, but also requires staff to work at heights, posing safety risks. More importantly, manual detection is periodic sampling inspection, making it difficult to capture real-time dynamic changes, and many potential problems are thus overlooked. The emergence of the TLKS-PLGS Transmission Line Grounding Resistance Visual Monitoring System is like equipping the power grid with an intelligent guardian unit, which has reconstructed the operation and maintenance logic of power equipment with innovative technologies.

2. Product Overview

The TLKS-PLGS Transmission Line Grounding Resistance Visual Monitoring System integrates cutting-edge on-site monitoring technology and cloud intelligent data analysis capabilities, building a full-time online monitoring system. Its breakthrough excitation pulse technology breaks through the limitations of traditional detection. It does not require power outage operations or additional electrode deployment to accurately obtain grounding resistance data.

When the system captures abnormal data fluctuations, it will immediately trigger an intelligent early warning mechanism and link with automated management functions, ensuring that operation and maintenance personnel can grasp the system dynamics in the first time and take timely countermeasures, building a solid protective barrier for the safe operation of the power system.

3. Working Principle

This monitoring device applies an excitation pulse to the grounding loop to generate potential E, and measures the loop current I at the same time. According to the formula R=E/I, the grounding resistance value is calculated in real time. This online measurement method completely breaks away from the dependence of traditional detection on power outage operations and auxiliary electrodes. It not only simplifies the detection process, but also greatly improves operation and maintenance efficiency and data accuracy, providing reliable data support for the refined management of power systems.
