THe direction of 3 phase induction motor can be reversed by
interchanging the connections i.e. if motor is connected to
3 phase as RYB now by connecting motor in RBY will result
in reversal of direction of motor as the direction of flux
is reversed by changing the connections

i have gear oil pump with single phase motor.some time its motor starts running in reverse direction rather than forward direction...whats the reason behind this issue. 1- either capacitor is week? 2- or winding is week?
Dear sir, In our plant have Station Transformer having capacity,i want to know, why LV side 40 - 40MVA is given? & how we can get 6.3 KV supply from tertiary(i.e. Open delta connection), Vector Group YNyn0 - yn0 +d MVA Rating 80MVA / 40 - 40MVA + 26.7MVA Voltage rating 420 (Tap range +6,to -10)81.25% /11.5KV - 11.5KV +6.3KV

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
