Benefits of Partial Discharge Test Equipment
Early Fault Detection
Identifies insulation faults before they develop into catastrophic failures. Through early fault detections, prompt repairs are possible, which adds to the overall life of the equipment.
Predictive Maintenance
Facilitates condition-based maintenance, enhancing reliability and reducing unexpected and costly downtime.
Extended Equipment Life
Helps maintain and prolong electrical equipment’s lifespan. Reduces wear and tear caused by undetected insulation damage.
Risk Reduction and Safety Enhancement
Identifying and mitigating PD activity reduces the risk of catastrophic failures, electrical faults, and safety hazards.
Cost Savings
Minimizes repair costs and unplanned outages through early detection of potential issues.
Application of Partial Discharge Test Equipment
Power Industry
In the power industry, partial discharge test equipment is mainly used to detect the insulation status of high-voltage switchgear, ring network cabinet, voltage/current transformer, transformer (including dry-type transformer), GIS (gas insulated switchgear), overhead lines and cables.
Railway System
In the railway system, partial discharge test equipment is used to detect the insulation status of power equipment and signal equipment along the railway, such as traction transformers, signal power transformers, cable lines, etc.
Petrochemical Power Supply System
In the petrochemical power supply system, partial discharge test equipment is used to detect the insulation status of power equipment such as transformers, cable lines, motors, etc. in petrochemical enterprises.
Aerospace Testing Field
In the aerospace testing field, partial discharge test equipment is used to detect the insulation status of electrical equipment on aerospace vehicles, including generators, motors, cable lines, etc.
Tips for Selecting the Right Partial Discharge Test Equipment
Choosing the right partial discharge test equipment depends on several factors. Here are some key criteria to consider:
Measurement Range and Sensitivity
Ensure that the partial discharge test equipment covers the required measurement range and sensitivity for your applications. The measurement range can vary depending on the device type.
User-Friendliness and Interface
The device should provide an easy-to-use interface that allows for quick and simple measurements.
Frequency Analysis and Localization
If you need detailed information about the source of partial discharges, choose a device that offers frequency analysis and the ability to locate discharges.
Certifications and Standards
Ensure that the partial discharge test equipment complies with relevant safety standards and is certified for reliable and accurate measurement.
Portability and Durability
If you need to use the device on-site, ensure that it is portable and durable to provide reliable performance even in harsh conditions.
Partial Discharge Test Equipment Safety Tips
The operation and maintenance of the partial discharge tester should be carried out by competent professionals.
There should be obvious and clear warning signs in the test area, and anyone on site should be aware of the high voltage area. During the test and after power on, no one is allowed to enter the high voltage area.
Before the test, the operator should master the test circuit, test method, test procedure and test purpose.
The test site should be neat and clean, and other irrelevant items should not be stored.
The surface of the tested product, step-up transformer, coupling capacitor, etc. should be kept dry and clean, because the moisture and dirt on the surface will cause partial discharge on the surface, resulting in abnormal measurement.
The test operators connect the lines according to the requirements of the regulations. Pay special attention to whether various ground wires are well grounded.
Before the test starts to pressurize, the test personnel must check the circuit in detail and comprehensively to avoid wrong connection of the circuit.
When the test is abnormal, the power supply should be cut off first, and then further processing should be carried out.
