Resistance testing continues to play an important role in transformer commissioning, routine maintenance, and condition assessment. As power networks become more complex and the demand for reliable electricity continues to grow, utilities and electrical service companies are placing greater emphasis on accurate, efficient, and reliable testing solutions.
Transformer winding resistance testing can help identify abnormal winding connections, poor electrical contacts, loose connections, and other potential issues that may affect transformer performance. Contact resistance testing is also widely used to evaluate circuit breakers, switchgear, and other high-current electrical connections.
Modern resistance testing technology is developing toward higher test currents, faster measurements, automated data processing, improved safety, and greater portability. These developments allow engineers to complete field testing more efficiently while obtaining more consistent and reliable test data.
