Problems solved by technology

However, due to the lack of industry standards and factory test standards for the current online detection methods for electrical equipment, some functional indicators cannot be tested, and the probability of failure of electrical equipment on site is low, it is difficult for the online detection device to capture the failure of the electrical equipment under test during operation , the function and accuracy of its online detection method and device cannot be verified

Since the performance of the on-line detection method and device cannot be verified when leaving the factory, this also raises doubts for users whether the on-line detection device of electrical equipment meets its performance indicators, so it is urgent to develop a laboratory simulation test method for the on-line detection device of electrical equipment It is used to verify the correctness, sensitivity and accuracy of the online detection device of electrical equipment, and solve the research test and factory test of the current online detection device of electrical equipment
