In electrical generators, the armature winding is distributed instead of concentrated.fpc winding displacement Since the coils are separated by an angular displacement, the induced emf per pole side is not the arithmetic sum of these induced emfs, as it would be if the armature winding were concentrated. Therefore, the induced voltage waveform generated by a distributed winding is not as smooth as that of a concentrated winding. This makes it difficult to detect a short circuit by analyzing the induced voltaage waveform. This article describes a method for detecting a short circuit in an alternator using an inductive test. The patented method uses an FPC sensor to measure the induced voltaage waveform in a power transformer, and the results are analyzed by comparing them with a reference signal. The resulting amplitudes of the measured signals are used to detect a short circuit, and the sensor can also be used to calculate the root cause of the short circuit.

An axial displacement (AD) of a power-transformer winding is one of the major causes of catastrophic electric faults in power transformers, such as turn-to-torn shorts and ground faults.fpc winding displacement The amount of AD is usually a few percent of the total winding height, and it cannot be detected by conventional methods based on analyzing a change in the transfer function (TF) of an interwinding measurement. A quantitative diagnostic method based on frequency response analysis has been proposed for AD detection, but it requires fingerprint data and cannot be applied to the case of a power transformer with a non-standard TF pattern.

The present utility model provides a kind of FPC winding displacement male seat connector, which can ensure stable transfer of signal without the need to arrange terminal and reduces the volume of the connector. This connector is characterized in that, the connecting body 1 includes an elastic component to bear the pulling force upwards by pressing plate 2 from past pull-up. The top board 12 of the connecting body is positioned to prevent the abutment of pressing plate 2 and the male seat connector by being come off toward pull-up, so that the connector can reach and prevent the object of pressing plate 2. In addition, the thickness of the front portion of the connecting plate is greater than the rear portion. This improves the bending resistance effect of the male seat connector and enables it to resist the impact caused by the magnetic field. It also improves the reliability of the connection between the connector and the press plate. Furthermore, the connecting body 1 is designed to prevent the contact between the pressing plate and the magnetic bearing winding, which can lead to an undesired electromagnetic interference. The resulting connector is highly reliable and easy to operate, which can significantly raise the yield of transformers. This is a significant advantage over existing technologies.
