As an important part of the power system, the transformer plays an important role in stepping up and down the voltage to ensure the safety of electricity use. Transformers that have been in operation for a period of time need to be tested regularly to prevent major failures. Therefore, a transformer no-load short-circuit tester is essential.

[0003] The transformer no-load short-circuit tester replaces the traditional power tester, has the advantages of fast measurement speed, high accuracy, and easy use, and is suitable for on-site detection. During use, one end of the device is connected to the detector and the other end is connected to the transformer to be tested for detection. After the detection is completed, the existing no-load short-circuit tester lacks a cable storage device, which easily causes the cable to become tangled and shortens the service life of the cable. In addition, the existing equipment requires manual transportation by the user, which is very inconvenient. Therefore, a distribution transformer synchronous measurement device is proposed to solve the above-mentioned problems. Utility Model Content
