241. Transformer Core Saturation Fault Analysis using Current Sensor Signals and Thermal Image Features
Year: 2023, Volume: 23, Number: 4
... feature extraction. measurement of the current signal. CT saturation leads to the inability in detection of actual faults. CT signals are I. INTRODUCTION influenced by ambient noise and electromagnetic Quality electric power supply distribution to consumer interference (EMI). Many sources introduce noise or relies on distribution transformer. When compared with oil- ...

... presentation of squared error as bias-variance data. That is to say, one instance among original instances decomposition is shown in Eq. (26). When the noise is becomes the validation instance while the remaining omitted, mean squared error becomes Eq. (27). instances are used as training instances. This method ...

... characteristics of the NI 6008 USB DAQ, using one of the 8 analog inputs (12b, 10kS/s) since the resolution is enough for the intrinsic noise of the temperature sensor LM35Z and the acquisition speed is enough given our thermal time constants. There are also available 2 analog outputs with lower speed, and ...

... with and without the laser line projection). The resulting image contains only the extracted laser line. In order to reduce the unwanted "salt and pepper" noise from the image an extra median filter is applied. Further on the process of edge thresholding if performed that leads to a clearer outline of the projected laser ...
