1、 Power system maintenance and testing

Power grid equipment testing: used for monitoring the insulation status of high-voltage transmission lines, power transformers, generators and other equipment to ensure the safety of the power grid. For example, detecting the insulation resistance (≥ 400M Ω) between the conductor and shielding layer of 10kV cables, as well as the insulation resistance (≥ 1000M Ω) of the upper and lower pile heads of lightning arresters.

Acceptance and maintenance of power equipment: Regular testing of power equipment after installation or during operation, such as detecting the insulation resistance (≥ 1000M Ω) of the circuit breaker in the open state on the detection column, to prevent short circuits or leakage caused by insulation aging.

Smart Grid and New Energy: With the increasing demand for grid connection of new energy sources such as wind power and photovoltaics, insulation resistance meters are used to detect the insulation performance of inverters, energy storage systems, and other equipment, supporting the efficient operation of smart grids.

2、 Industrial Manufacturing and Automation

Electrical equipment production: Insulation quality testing is carried out on equipment such as motors, transformers, and switchgear before leaving the factory to ensure compliance with safety standards. For example, the overall insulation resistance of the complete bypass equipment should be ≥ 500M Ω.

Industrial production line monitoring: integrated into automation systems, real-time monitoring of the insulation status of electrical equipment on the production line to prevent shutdown accidents caused by equipment failures. Industrial insulation resistance meters need to have the ability to resist electromagnetic interference.

Petrochemical and Metallurgy: Testing the insulation performance of pipelines and containers in high temperature, high humidity, or corrosive environments to ensure production safety. For example, the grounding resistance of chemical equipment needs to be measured using a low resistance meter.

3、 Transportation and Infrastructure

Rail transit: used for insulation testing of traction power supply systems such as subways and high-speed trains. For example, the insulation resistance between overhead line conductors and iron crossarms should be ≥ 300M Ω.

Aerospace: Testing the insulation performance of aircraft electrical systems (such as avionics equipment and cables) to meet high-precision and high reliability requirements, ensuring flight safety.

Electric vehicles: Used for measuring insulation resistance of power battery packs and charging stations in new energy vehicles to prevent high-voltage leakage risks. For example, the battery management system needs to regularly check the insulation status.

4、 Research and Laboratory Applications

Material research: Evaluate the voltage resistance characteristics of materials such as insulating oil and insulating paper, and support the development of new insulation materials. A high resistance meter can detect microampere leakage current.

Complex experimental scenarios: used in disciplines such as physical chemistry and electrical engineering for multi parameter testing (such as temperature coefficient and voltage resistance), combined with data storage functions to record experimental data.

5、 Emerging fields and intelligent trends

Intelligent operation and maintenance: The insulation resistance meter integrated with IoT technology can remotely monitor equipment status and achieve predictive maintenance. For example, transmitting data to the cloud for analysis via Bluetooth to provide early warning of insulation degradation.

Multi functional integration: High end products integrate insulation resistance, grounding resistance, capacitance and other multifunctional tests to meet the needs of complex scenarios such as urban utility tunnels and data centers.
