情境
A three-phase transformer bank is wired with primary windings in star and secondary windings in delta, providing a primary neutral and a standard 3-wire delta secondary.
這張圖裡有什麼
看懂背後的決策。
01
Ground the primary star point using net 0 for a stable reference
02
Connect secondary windings in a closed delta loop across terminals U, V, W
03
Add balanced line-to-line resistor loads to complete the secondary circuit
Use when a 3-phase transformer needs a neutral on the primary side but a standard delta service on the secondary; reconnect winding ends for star-star or delta-delta variants.
