Single Phase Transformer Autotransformers

Auto Transformer
from Powertronix Corp.

Auto Transformers are single winding toroidal transformers for voltage step up or step down, when there is no requirement for electrical isolation. Auto Transformers offer a significant size and weight reduction as well as lower cost. APPLICATIONS. Industrial Automation. Electrical Equipment [See More]

Step-Up/Step-Down Autotransformer -- N-1X
from Triad Magnetics

Description. Triad autotransformers are single winding single phase transformers in which the primary coil is a fraction of the entire winding for voltage step-up or the secondary coil is a fraction of the entire winding for voltage step-down. In ordinary double wound power transformers, the primary... [See More]

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]
