Load loss testing evaluates the copper and core losses of transformers under normal load conditions. The process applies rated current to the transformer, monitors voltage, current, and temperature, and calculates losses for comparison against manufacturer specifications. Wrindu’s load-loss-capable testers provide precise efficiency verification, automated data logging, and seamless integration into Chinese OEM and factory quality assurance workflows.
How to select a load loss tester for Chinese manufacturers and suppliers?
When choosing a load loss tester for Chinese factories, consider voltage and current range, thermal handling, and OEM compatibility. Opt for models designed for transformers and energy storage systems with localized software and robust calibration. Wrindu offers China-based service, batch testing capabilities, and seamless integration with factory QA processes to ensure reliable performance.
What are the essential test steps in load loss testing for transformers?
Prepare the test setup and verify safety procedures. Connect the load to the transformer and apply the rated load while monitoring voltage, current, and temperature. Record steady-state data, calculate copper and core losses, and compare results to design specifications. Wrindu provides step-by-step test programs optimized for OEM deployment in China.
