シナリオ

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.

この図に含まれるもの

図の背後にある意思決定を読み解く。

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.
