The power transformer is star connected on one side and delta connected on the other side. The CTs on the star connected side are delta-connected and those on delta-connected side are star-connected. The neutral of the current transformer star connection and power transformer star connections are grounded.
DOL Starter: In a DOL starter, the motor is directly connected to the full voltage of the power supply during the start. This results in a sudden and high starting current. Star-Delta Starter: In a Star-Delta starter, the motor is initially connected in a star configuration during the start, which reduces the voltage across each winding.

スターとデルタは、三相システムの XNUMX 種類の接続です。 スター接続では、各相 (またはコイル) の一端が互いに接続され、「中性点」として知られる共通点を形成します。一方、デルタ接続では、各相 (またはコイル) の端がループ状に互いに接続されます。 。
To summarize, in star connection, the line voltages are apart from each other (phase voltages are also apart from each other); line voltages are ahead of their respective phase voltage (refer to Figure 3); the angle between the line currents and the corresponding line voltage is with current lagging by an angle (for lagging loads).
