diffuser increases pressure but in turbine pressure is
decreasing when steam passing through casing?

Answer Posted / mohan tayade

diffuser has diverging area while turbine casing has
converging area ,and we know that in converging area the
velocity will increase and pressure will decrease ,in case
of diverging area reverse of it will take place

and the draft tube which is at the delivery port of the
turbine also be one reason of theat

A very strange fault i cam across today,that i never experienced not studied before, i need an answer for this. Phase to phase or line to line , L1,L2 & L3, voltages are 490VAC, but if i use line to ground , its again 490 VAC. . . whats the fault and theory behind of it?
