The star-delta calculator is used to calculate the conversion between star and delta network. In This app to calculate the total resistance between star and delta network. Standard 3-phase circuits or networks take on two major forms with names that represent the way in which the resistances are connected, a Star connected network which has the symbol of the letter, ? (wye) and a Delta connected network which has the symbol of a triangle, ? (delta). If a 3-phase, 3-wire supply or even a 3-phase load is connected in one type of configuration, it can be easily transformed or changed it into an equivalent configuration of the other type by using either the Star Delta Transformation or Delta Star Transformation process.
