480v to 120v transformer connections
STEP BY STEP
If you want run RV using fixed transformer 230V to 120V with high watt rated, no problem at all. A Variac (variable transformer) is to replace normal step down transformer. You don't have to buy normal transformer if you use a variac. The primary input will be 230V (house power). The secondary you can set between 0V to 270V.

One or three transformers can be installed depending the required kVA rating. The primary is normally connected from phase to ground. Typical secondary ratings available 120/240V, 277/480V, 240/480V and 600 VAC. Transformer Connections: Depending on number of transformer selected for station power applications two types of connections are employed:

Transformer connections affect the propagation of positive, negative, and zero sequence components differently. Thus, the characteristics of a voltage sag changes as it propagates through a network. Typically, a transmission voltage sag passes through two levels of transformers before reaching a 480V load (e.g., 138kV:12.47kV at the entrance to ...
