Above Figure Shows Standard Test Circuit to Test CMR of Transformer...
a) 'eCM'=Sine Wave,Is 'eo' also Sine Wave
b) If 'C' were grounded instead fo 'R';does 'eo' remain same?
c) Is CMR due to Asymmetry of Inter-winding Capacitance of Transformer.
Below Shows IEEE standardized equivalent circuit of a pulse transformer.
Why is the Circuit Asymmetrical w.r.t Rcu1,2 ,L(sig)1,2 ,C12?
