Hi, my friends
Let me quote Floyd Sweet :
This wire is specially insulated, and over this insulation is wound a current feedback winding spirally traversing the total length of the coil conductor. Also a voltage winding of considerably smaller wire and more turns is also wound axially, traversing the total length of the coil conductor.
What is he talking about?
Could it be about the Rogowsky coil ?
The respective leads are brought out to terminals, and to these terminals is connected the output of the current and voltage sensing transformers.
What is Floyd Sweet doing with current and voltage sensing transformers?
We now have, when the current and voltage windings are excited, another set of fields virtually in quadrature with the fields (alternating) initiated by the load current flowing in the power phase coils.
What does "virtually in quadrature" mean? Like 90 degrees shift between the waves or like 2 coils physically orthogonal to each other?
The current and voltage initiating fields are in such a direction to either accelerate or decelerate the rate of flow of charges depending on the applied polarity and voltage amplitude.
My brain is on fire! Some experiments are needed.
