In the power system, the insulation performance of cables is directly related to the safety and stability of operation. And the cable leakage detector is an important guardian of this "lifeline". It can promptly detect small cracks or aging in the insulation layer of cables, preventing equipment damage or even safety accidents caused by leakage. How should we choose and make better use of the dazzling array of products on the market?
What is a cable leakage detector?
Simply put, a cable leakage detector is a professional equipment used to detect leakage phenomena caused by poor insulation of cables. It determines the insulation status of cables by measuring parameters such as insulation resistance and leakage current. Once the insulation resistance falls below the safety threshold or abnormal leakage current is detected, the equipment will sound an alarm.
Factors affecting the accuracy of cable leakage detection
Environmental factors: harsh environments such as humidity, high temperature, and dust can affect the accuracy of instrument readings and may also accelerate cable insulation aging.
The condition of the cable itself: the material, service life, laying method, and whether there is physical damage of the cable will all affect the difficulty and results of leakage detection.
Instrument performance: Different models of cable leakage detectors have differences in sensitivity, accuracy, anti-interference ability, and other aspects.

1. How to choose?
Clear detection requirements: Is it for daily inspections or for in-depth investigations in specific areas? The requirements determine the accuracy and functionality of the instruments you need.
Pay attention to measurement range and accuracy: Ensure that the measurement range of the instrument can cover the parameters you are concerned about, and the accuracy meets industry standards.
Considering usability and security: Is the user interface intuitive? Are there comprehensive safety measures in place?
2. How to use it?
Regular calibration: Ensure that the instrument is in optimal working condition, regularly send it for inspection or self calibrate.
Standardized operating procedures: Strictly follow the instructions for operation, especially in high-pressure environments.
Combining multiple detection methods: Cable leakage detection not only relies on one instrument, but also combines infrared thermal imaging, partial discharge detection and other methods to more comprehensively evaluate the health status of cables.
3. How can we do better?
Establish a comprehensive cable file: Record detailed information about each cable, including installation date, usage environment, previous testing data, etc., to facilitate trend analysis.
Strengthen preventive maintenance: Through regular insulation resistance testing and inspections, potential problems can be identified and addressed in a timely manner to nip faults in the bud.
Continuous learning and training: Focus on the latest technology and testing methods in the industry to enhance the professional skills of testing personnel.
Frequently Asked Questions (FAQ)
Q: How often does the cable leakage detector need to be tested? A: This depends on the usage environment and importance of the cable. It is usually recommended to conduct a comprehensive inspection at least once a year, and high-risk areas can increase the frequency of inspection.
Q: Can a leakage detector detect all types of cables? A: Most leakage detectors are suitable for common power cables, but for some special materials or high voltage level cables, specialized models may be required.
Q: Why is my detector reading unstable? A: Unstable readings may be caused by environmental interference, instrument calibration issues, or dynamic leakage points in the cable itself, and need to be investigated one by one.
Q: What should I do after detecting a leakage? A: Immediately stop using the cable and have it thoroughly inspected and repaired by professional personnel. Do not operate it with any problems.
