Übersetzung für 'star-delta connection' von Englisch nach Deutsch

star-delta connection

Stern-Dreieck-Schaltung {f}electr.

• Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components.
• As in the case of the conventional linear winding technology, a contact pin or a hook contact can be terminated for the electrical connection and for interconnecting the single poles in a star connection or delta connection.
• The windings of a 3 phase alternator may be connected using either the "delta" or "star" ("wye") connection regime set-up.
• On the 50 Hz side, two 275/54 kV transformers, in separate tanks, feed the valves, again with one in delta and the other in star connection of the low-voltage windings.
• The motors employ a double-star type connection; if a traction inverter is inoperative (i.e. due to a failure) the motors use a delta-type connection and are fed by only one inverter.

• In electrical engineering, a vector group, officially called a connection symbol, is the International Electrotechnical Commission (IEC) method of categorizing the high voltage (HV) windings and low voltage (LV) winding configurations of three-phase transformers.
• It is used for large motors, in which start by direct connection to the network is not possible.
• Simple forms of this distribution/connection model contrast with point-to-point transit systems, in which each point has a direct route to every other point, and which modeled the principal method of transporting passengers and freight until the 1970s.
