Can we parallel lise the secondary side of the two similiar
transformers with same voltage ration, imp, but with
different vector groups.. ( for ex. 11 KV / 6.6KV two
trfs but different vector groups can we parallelise both of
them ,, what happens if we parallelise them
Answer Posted / jitendra kumar
We cant parallise without same vector.If we parallise then
it may possible transformer output imbalance.

Dear all, I just want to ask an expert on this forum for some insights. For the magnetic balance test, when applied voltage on a Delta-Star transformer e.g. Dyn11, the following relationships apply for HV side: 1. H1-H2 = H2-H3 H3-H1 2. H2-H3 = H3-H1 H1-H2 3. H3-H1 = H1-H2 H2-H3 For the LV side also: 4. X1-X0 = X2-X0 X3-X0 5. X2-X0 = X3-X0 X1-X0 6. X3-X0 = X1-X0 X2-X0 Is there a similar pattern for Y-d, Y-Y, D-d? And how about Y-z, D-z, Z-y transformers? I've tested a YNzn5 transformer and for LV side I don't see the pattern. In this particular case I got for LV side the following (see values below): H1-H0 H2-H0 H3-H0 X0-X1 X0-X2 X0-X3 128.0 119.9 7.2 29.2 13.3 15.8 70.7 128.4 59.2 23.4 22.0 3.6 7.2 120.1 128.1 13.4 29.3 15.8 What is the relationship here for LV? For row 1 I see the relationship, for row 3 I also see but it's shifted, but for row 2 I don't see such relationship. Any suggestions, answers, someone?

sir,in our plant we r using SATEC PM172E power reading meeters in HT panel side it is monitoring the MB data smart viewer(sever).but last one week we did not get readings inthe server only available in meeter.tell me how communicate meter and server. and also what steps we take for checking.
