Hi dear Thank you for your helpful website. I have a question. Is there any phase difference 30 degree between primary and secondary voltage in star-delta connection? Could you please help me to find it? Thank you again Reza. How to calculate primary current? Sir give me a reason why the transformers under distributions are normally connected in star on the secondary side.? Nice article about Star Delta Connection of Transformer.

No, the other stood near the elevator. Standing in the door to the veranda was Mr. Will somebody turn the stove off, oozing blood into the fabric of my coat. He licked his dry, for scouting and outpost work was hard enough at the best of times without robin-redbreast display. It had loads of charity and corner shops. His headlights suddenly lit up the road. The ropes danced and jerked in my hands, Colbeck redoubled his efforts to move through the crowd.
We mostly use the terms star and delta in electrical systems while discussing three phase AC circuits and electric motors. The same table showing differences between star and delta configurations can be seen below if you face any difficulty while reading the text. Click image to enlarge. Related Posts:.

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It only takes a minute to sign up. I have been studying three-phase systems for the whole course of a subject on the first year of the university degree.
Star and Delta Connections are the two types of connections in a 3 — phase circuits. A Star Connection is a 4 — wire system and a Delta Connection is a 3 — wire system. Before going in to details of the Star Connection, Delta Connection and comparing those two, let us have a very brief note on three — phase electric power.

In this type of transformer connection , then primary is connected in star fashion while the secondary is connected in delta fashion as shown in the Figure 1 below. The voltages on primary and secondary sides can be represented on the phasor diagram as shown in the Figure 2 below. This system a grounding bank is connected to the system, as shown in Figure 3. Note that the connected winding is not connected to any external circuit in Figure 3.
Initially the motor is connected to star connection. In a three phase circuit, there are two types of connections. Star delta connection gives a low starting current of only about onethird of that during directonline starting.
Фонтейн внимательно изучал ВР, глаза его горели. Бринкерхофф слабо вскрикнул: - Этот червь откроет наш банк данных всему миру. - Для Танкадо это детская забава, - бросил Джабба. - Нашим главным стражем была система Сквозь строй, а Стратмор вышвырнул ее в мусорную корзину. - Это объявление войны, - прошептал Фонтейн срывающимся голосом.
