Passage of High-Frequency Signals through Power Transformers.

Research output: Contribution to journalArticlepeer-review


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.
