High Current Output: To overcome the effects of contact resistance and lead resistance, many loop resistance testers can output high currents of up to several hundred amperes, thereby obtaining more accurate measurement results.
Fast Measurement: Uses advanced measurement technology to complete resistance value measurements in a short time, improving work efficiency.
Portability: Modern loop resistance testers feature compact design and light weight, making them easy to carry to the site for testing work.
Application Scenarios
Power Transformer Maintenance: Regularly measuring the DC resistance of transformer windings is one of the important steps in assessing their condition, helping to detect issues such as broken strands or poor contact in windings.
Switchgear Inspection: Performs contact resistance testing on key components such as circuit breakers and disconnect switches inside high-voltage switchgear to ensure good contact and avoid overheating caused by poor contact.
Cable Joint Testing: After installing or repairing cables, uses loop resistance testers to verify joint quality and ensure current transmission efficiency.
Motor and Generator Inspection: Determines whether short circuits or open circuits exist by measuring the resistance of motor or generator windings, ensuring normal motor operation.
