1. Handover acceptance and preventive testing: Before the installation and operation of new equipment or during regular maintenance, measure the DC resistance of its conductive circuit and check whether the contact condition of the connecting parts is good. This is one of the most basic and important testing items for power equipment.

 

2. Evaluate the connection status and degradation trend: Through longitudinal comparison of previous test results, effectively discover the increasing trend of resistance caused by contact surface oxidation, looseness, contact electrical wear, etc., and timely warn potential faults.

 

3. Fault location and repair verification: When the equipment overheats or has insufficient current carrying capacity, it is used to accurately locate the specific connection point where the resistance abnormally increases, and verify the repair effect after maintenance.

 

The Circuit Breaker Contact Resistance Tester is mainly used to measure the contact resistance of electrical equipment such as high-voltage circuit breakers, isolating switches, busbars, cable joints, and switchgear. It is widely used in power plants, substations, power maintenance, and electrical equipment manufacturing industries. By detecting the contact status of the conductive circuit, problems such as poor contact and heat hazards can be detected in a timely manner, ensuring the safe and stable operation of power equipment.

 

 

1. Disruptive efficiency improvement: Testing speed increased by 50%

Traditional methods are time-consuming and labor-intensive. Our instrument adopts advanced high-frequency switching power supply technology and intelligent pulse testing method:

Fast charging and discharging: The test current (100A/200A/600A optional) can be stably output in just 3 seconds, reducing the testing cycle by half.

One click intelligent operation: No need for complex parameter settings, press "Test" once and the results will be displayed within 5 seconds.

Procurement value: Reduce labor costs and significantly improve on-site inspection efficiency.

 

2. Ultimate safety and intelligent protection: No longer have to worry about burning out instruments

The on-site environment is complex, and misoperations often occur.

Multiple protection mechanisms: overvoltage, overcurrent, overheating, reverse connection automatic power-off protection.

Strong load capacity: Even if the resistance of the test line is as high as 200m Ω, it can still output the rated stable current.

Purchase value: Extend the lifespan of the instrument, ensure the safety of operators, and reduce the company's hidden risk costs.

 

3. Comprehensive data management: on-site printing+cloud upload

Built in large capacity storage, equipped with high-speed thermal printer, on-site printing and labeling.

Supports RS232/USB/Bluetooth communication interface, and data can be seamlessly imported into the backend or power equipment management system.

Procurement value: Easily issue formal test reports, meet ISO and CETC audit requirements, and end the era of handwritten data.

 

4. Rock solid reliability: specially designed for extreme working conditions

Waterproof and dustproof rating IP67 (optional), anti drop chassis.

The working temperature ranges from -10 ℃ to+40 ℃, meeting the requirements for field operations throughout the year.

Procurement value: A device that has been in service for over 10 years and has an extremely low overall cost of ownership.
