According to IEC and relevant national standards, the transformer turns ratio test is a mandatory item during the production, user acceptance, and maintenance testing of power transformers. This effectively monitors the quality of transformer products during manufacturing and use, preventing inter-turn short circuits, open circuits, connection errors, internal faults or contact faults of tap changers. Therefore, our company has developed and produced a fully automatic turns ratio tester based on the original design, incorporating user field requirements to make operation simpler, functions complete, data stable and reliable, and testing speed greatly improved. It meets the needs of turns ratio testing for various large, medium, and small transformers.
