What do you mean by star delta connection?
A star connection is one with 3 hot conductors returning power to a (usually grounded) common return (neutral) conductor. If the three hots are called A, B, and C, and the neutral is called N, then...

Why we need to do star connection?
Usually star connections are needed in places where lots of peripheral connectors have to be made. these types of circuits are most common in domestic power connections in highly crowded and power...

When is a motor in star connection or in delta connection?
Star (or wye) connection is where each of the three phases has a fourth conductor, neutral, as its current return. Current flow in this configuration is phase to neutral, which is also grounded back...

How do you connect star delta connection?
Star and Delta is used mostly in 3 pH networks where 3 phases are 120 degrees apart. consider A1-A2,B1-B2, C1-C2 as three different wdgs or resistors. for star connection connect A2,B2,C2 together...

Why you use the star delta connection?
Motors pull a lot of starting current, sometimes as much as four times their running current. This can damage components and/or make the motor overheat. Star-delta is a technique that can reduce this...
