Substation Transformers

Robustly engineered and manufactured substation transformers are uniquely designed for reliable substation service. Liquid-filled transformers converting transmission voltages to distribution voltages are a common transformer type produced by Niagara. These transformers can be with or without on-load tap changers or other protective devices such as primary and secondary arresters and breakers, as well as being integrated with switches, or expansive SCADA output data for remote operator monitoring.
