'Bridge Measurement Circuits - info sought'
|I'm attempting to measure LCR (particularly L & C) in electrically complex
eg inductors with open magnetic paths, various cable stubs etc.
Commercial meters / bridges exist to do the hard work for you.
I'd like to avoid making Messrs HP or Wayne-Kerr richer if possible.
Has anyone got links for the various traditional bridge circuits for
I dimly recall a very capable version (Marconi?) which allowed determination
of all parameters for either L or C.
Diagonally opposing legs were AFAIR R in series with L in one leg and R in
parallel with C in the other plus pure R's in the other 2 legs. Basic
calculations fail to produce useful balance conditions for this combination
so I have probably missed a key point.
Anyone got any useful information.
(Perhaps an auto balance version utilising a PIC could be built :-))
What can one unbalanced person do?
Help the hungry at no cost to yourself!
