System Intertie Autotransformers
from ABB Power Products/Power Systems

Substation autotransformers transfer the incoming high voltage to the next lower voltage level. As an example, incoming high voltage of 400 kV would be transferred down to 220 kV. In general substation autotransformers are equipped with on-load-tap changers (OLTC). Incoming transmission lines are... [See More]
