The Wye and Delta three phase configuration each have their uses. This video gives a brief overview of the difference between the two and why it matters.🤳a What is Star and Delta connection in 3 phase system | Complete explanation in UrduHere is an another electrical engineering basics lecture in which I complet The method shown in at figure 1a is known as a delta connection and figure 1b as the star or wye connection. Differences between wye and delta connection in that wye connection has two phases in series. Two Wattmeter method can be employed to measure the power in a 3 phase, 3 wire star or delta connected balanced or unbalanced load. In Two wattmeter method the current coils of the wattmeter are connected with any two lines, say R and Y and the potential coil of each wattmeter is joined across the same line and the third line. A Three Phase Power Supply consists of three power wires (or the three phases). Additionally, depending on the type of the circuit (which there are two types: Star and Delta), you might or might not have a neutral wire. In a three phase power supply system, each AC Power Signal is 120 0 out of phase with each other. The difference between Star & Delta connection Star Connection 1- Use for low voltage 2- it give : 220 v , 380 v 3- There is a Neutral or star point Delta Connection 1- Use for High voltage 2- it give : 400v or more 3- No Neutral point in delta connection Star Connected System: Star connection is used where we require Neutral terminal to obtain Phase voltage like above below. In a star connected system VL=√3Vph, mean Phase voltage is root 3 times less than line voltage. In a star Connected system IL=Iphase. Star connected systems require less insulation level. Star Connected system is used Open Delta Connection is a method of transformer connection used to transform three-phase power using two single-phase transformers.In this article, you will learn how this connection is done and the theory behind this.The Scott connection is another method used for the same purpose of transforming 3 phase power using two single-phase transformers.Both of these methods result in slightly 76q2q.
