why the earth terminal in three pin top is longer than rest
of the two terminal and of bigger size?
Answer Posted / bhatt
As we know earth is connected to the body of
equiment/machine hence if earth terminal is longer then
earth will be connected to body of equipment/machine first
thereafter phase and neutral. It is bigger size because it
must not go in phase & neutral terminal by any mistake so
as to avoid any direct contact of body of machine with
phase/neutral.

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?
