I want Primary side delta and Sec side Star connection transformer . but i have received Star - Star transformer ,shall i use the same transformer by giving the only 3 ph on Primary side without Neutral connection on the Starpoint.
5 11669Why current flows in nutral? As per theory there should be no current in 3 ph explain.

2 6485If the capacitor bank is installed in switchyard say 132/22kv then on LT side say 22kv/0.433kv is it necessary to install capacitor bank for maintaining power factor. if pf is maintained on HT side then will that be maintained on LT side as well.if not then how&why??????/ please explain...........

Explain and give me an example of a time when you had to explain some new procedures to your co-workers for quality service delivery, how did you go about it?
What are the components connected in between the power supply coming from an electric pole to HT & LT Panels in a large commercial building or how the power supply connected from Electric pole to Transformer & then to the HT & LT panels of a building? Please send me answers via mail, my id is yogiagarwal@gmail.com. If possible, please give a line diagram.
As per the Anchor capstan motor specification, full load current is 200A. starting current is 1750 A and acceleration time is less than 8 seconds. Please guide for selection of cable size.
Why induction motor is widely used in industry
I have doubt that the supply HZ (very low or high than rated ) may affect the power factor. is it true. ?

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
