When an external short-circuit fault occurs, the transformer windings will be subjected to short-circuit electromagnetic force, and accidents such as winding tiltiing and buckling will occur, which ...
Push-Pull Transformer Driver ICs There are a vast number of oscillator/power-driver ICs specifically designed for small form factor, isolated power supplies in isolated interface applications. Such an ...
Monitoring of winding hot-spot temperature and dissolved gas-in-oil and furan-in-oil provides a major support to the operator when the transformer faces overload conditions. On-line monitoring of ...
By analyzing the frequency response of different breakdown current signals measured at the end of the transformer winding, support vector machine is used to identify the breakdown position of the ...
Design of a transformer As a static electric machine, the transformer implements a transformation of the voltage and current ratios between the primary and the secondary, trying to maintain the power ...
Figure 2 shows the circuit diagram of one representative example of the transformer-based VR. The VR circuit features a step-down transformer with two secondary windings and a current doubler ...
In this paper, the digital twin of transformer winding is established based on double ladder network, in which the distributed parameters are calculated by finite element method. Frequency response ...
This test set uniquely combines winding resistance measurement, transformer turns ratio, tap changer dynamic resistance, core demagnetization, transformer type detection, magnetic balance, short ...
