## What is a Delta connection?

A delta connection is a connection used in a three-phase electrical system in which three elements in series form a triangle, the supply being input and output at the three junctions. In Delta (also denoted by Δ) system of interconnection, the starting ends of the three phases or coils are connected to the finishing ends of the coil. Or the starting end of the first coil is connected to the finishing end of the second coil and so on (for all three coils) and it looks like a closed mesh or circuit .

## How to Calculate Delta to Star transformation?

Delta to Star transformation calculator uses Star Impedance A = (Delta Impedance 1*Delta Impedance 3)/(Delta Impedance 1+Delta Impedance 2+Delta Impedance 3) to calculate the Star Impedance A, The Delta to Star transformation formula is defined as the transformation of impedance connected in a delta connection to star connection. It is done when the sum of adjacent impedances in star connection are summed up with the product of two adjacent impedances divided by the remaining one impedance. Star Impedance A is denoted by ZA symbol.
