Answer to Question #282140 in English for honey

Question

State the real-time applications of Star and delta connected 3 phase balanced loads. Also, derive the relationship between line and phase quantities when a 3-phase balanced delta connected load is connected to the 3 phase star supply.

Answer 1

The star and delta connected in 3 phase is applied when there is need for two separate voltages and a neutral it is usually used as suitable alternative when neutral conductor is unnecessary for transfer of high voltages. The relationship between line and phase quantities in the delta connection is that they both have the same voltage
