TY - JOUR T1 - Passage of High-Frequency Signals Through Power Transformers AU - A. A. LACEY JO - International Journal of Numerical Analysis Modeling Series B VL - 3 SP - 224 EP - 241 PY - 2012 DA - 2012/03 SN - 3 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/ijnamb/280.html KW - Homogenisation KW - thin layers KW - high frequency AB - We consider the possibility of passing high-frequency signals past power transformers forming part of an electrical grid. We first model a transformer, including its laminated core, to obtain asymptotic behaviour of currents and voltages in the secondary circuit. Having got this we are able to determine the effects of different by-pass mechanisms which might be tried to get the high-frequency signal from the primary to the secondary circuit.
