High Voltage Cable Circulation Online Monitoring System

Product Aliases: Cable Sheath Current Monitoring System, Cable Sheath Grounding Current Monitoring Device, High-Voltage Cable Circulating Current Online Monitoring System

TLKS-PLGDHigh-Voltage Cable Circulating Current Online Monitoring System stands out as the preferred device for intelligent operation and maintenance of high-voltage cables, thanks to its core advantages such as high-precision real-time monitoring, multi-scenario adaptive power supply, intelligent early warning and anti-theft, and remote visual operation and maintenance. Traditional detection of cable sheath circulating current mostly relies on regular manual inspections, which have drawbacks like data lag, large errors, inability to capture transient anomalies in real time, and high labor costs, making it difficult to predict hidden issues such as cable insulation aging, grounding faults, and ground wire theft in advance. This device realizes 24-hour uninterrupted online monitoring, can accurately capture subtle fluctuations in circulating current, automatically trigger anomaly warnings, and is equipped with dual power supply of solar energy and CT (current transformer) as well as wireless remote transmission functions. It adapts to complex scenarios such as cable trenches, tunnels, and outdoor manholes, completely making up for the shortcomings of traditional manual operation and maintenance, effectively improving the safety and stability of high-voltage cable operation, and is deeply favored by the power industry. Its core values are mainly reflected in the following aspects:

Working Principle

TLKS-PLGDHigh-Voltage Cable Circulating Current Online Monitoring System captures core operation data such as the waveform and amplitude of the grounding current of the metal sheath of high-voltage cables in real time through the front-end acquisition unit, and dynamically monitors the change status of circulating current around the clock. The device processes, screens and integrates the collected original data in real time, and synchronously uploads it to the background monitoring platform and the handheld devices of operation and maintenance personnel via the 4G wireless communication network. The system has an built-in intelligent judgment mechanism, which can accurately identify abnormal working conditions such as transient rise and sudden drop of circulating current, and also monitor the on-off status of the grounding wire. Once a fault, anomaly or ground wire theft is determined, it will immediately trigger an alarm and upload the fault point information. In addition, the device has self-diagnosis capability, can real-time check its own operation faults, and is equipped with data storage and analysis functions, realizing advance warning, fault traceability and status control of cables.

Core Functions

1.24/7 Online Monitoring: Collects the waveform and amplitude data of the grounding current of the metal sheath of high-voltage cables in real time, dynamically grasps the operation status of cables, and eliminates monitoring blind spots.

2.Intelligent Anomaly Alarm: Automatically triggers early warnings for abnormal working conditions such as transient rise and sudden drop of grounding current, and feeds back circulating current faults in a timely manner.

3.Ground Wire Anti-Theft Monitoring: Has the function of identifying grounding wire theft, can accurately determine the theft status and locate the fault point, and effectively prevent the grounding system of cables from being damaged by theft.

4.Device Self-Diagnosis: Real-time monitors the operation status of the device itself, automatically checks for device faults and uploads them to the platform, ensuring the stable and reliable operation of the monitoring system.

5.Remote Data Viewing: Relies on 2G/3G/4G wireless networks to push real-time monitoring data to handheld operation and maintenance devices, enabling remote operation and maintenance viewing anytime and anywhere.

6.Data Recording and Analysis: Automatically retains parameters such as daily monitoring data and fault records, providing data support for cable status analysis, traceability and operation and maintenance optimization.

7.Dual-Mode Adaptive Power Supply: Supports two modes of solar lithium battery power supply and CT power taking, adapting to complex on-site conditions such as outdoor areas, tunnels, and places without external power supply.

Application Value

TLKS-PLGDHigh-Voltage Cable Circulating Current Online Monitoring System completely changes the traditional mode of regular manual inspection of cable sheath circulating current, realizing 24-hour uninterrupted and intelligent monitoring of cable operation status. By accurately predicting circulating current anomalies, it effectively avoids problems such as cable overheating, insulation aging, and breakdown faults, extends the service life of cables, and reduces the probability of power grid faults and power outages. At the same time, the device integrates functions of ground wire anti-theft and device self-diagnosis, which can effectively prevent external damage and device failure, greatly reduce the frequency of manual inspections, and lower the operation and maintenance costs of the power grid. The remote data transmission and intelligent early warning functions help shift cable operation and maintenance from passive repair to active prediction, and promote the digital and refined upgrading of cable operation and maintenance management.
