AZWO
Current equalizing autotransformers AZWO
Application
Single-phase current equalizing autotransformers AZWO are designed to work with main transformers. They are used in the circuits of differential protections of power transformers.
Structure
Autotransformers AZWO have a wound core of RZS type. Core dimensions depend on the parameters of autotransformers. The core windings are impregnated with polyester resins which act as the main insulation.Autotransformers AZWO are provided with 6 terminals, both on a primary and secondary winding. The devices fully comply with the Technical Demands (WT/X.75)
