Transformer Double Voltage/ Double Frequency Testing

The linear transformer winding of medical electrical equipment needs to have sufficient insulation to prevent dangerous situations that may arise from overheating in internal short circuits. The transformer voltage and frequency doubling test, which evaluates quality and electrical safety characteristics, is one of the most important tests for safety of medical electrical products.

◉ Service Background

Transformer Voltage and Frequency Doubling：The linear transformer winding of medical electrical equipment needs to have sufficient insulation to prevent dangerous situations that may arise from overheating in internal short circuits. For transformer’s winding with rated voltage less than or equal to 500V, or rated frequency less than or equal to 60Hz, 5 times the rated voltage or maximum rated frequency will be will be used, applying a frequency not less than 5 times the rated frequency at both ends of the winding. During the testing process, the insulation should not be broken. The transformer voltage and frequency doubling test, which evaluates quality and electrical safety characteristics, is one of the most important tests for safety of medical electrical products

Medical device testing is the basis for medical devices to enter the global market. If a product is to be exported to the European Union or the United States, then corresponding tests will need to be done to meet the EU or US standards.
