[TCML] parallel operation of a single phase transformers.



i would like you to help me on this question,with full explanation in details .
what are the effects in practice of connecting transformers in parallel under the following conditioins .
1)different impedance ,same voltage ratios .2)different R/X ratios ,same voltage ratios.> Date: Tue, 15 Apr 2008 13:51:01 -0700> From: yurtle_t@xxxxxxxxx> Subject: Re: [TCML] Windings Repair - Should This Work?
