Abstract：If an isolation transformer is included in the LED control unit,different third-party certification bodies have different methods for measuring the operating voltage of the isolation transformer.The primary and secondary voltages of the isolation transformer can be measured directly,but how to determine the operating voltage between the primary and secondary stages of the isolation transformer?This paper analyzes this problem through the actual test data,combined with the standard requirements,etc.,and gives the final analysis results.The intention is to provide a clear and unified test method for the working voltage of the isolation transformer in the LED control gear for the product inspectors of lighting enterprises.At the same time,it also provides a reference for third-party certification body inspectors.
