Isolating transformers, 1TTS type for TS35 busbar
Purpose and design
Single-phase isolating transformers are designed to supply small electrical appliances when voltage isolation is required. Isolation is achieved by the use of double-chambered coils or a copper screen between the windings. The design of the single-phase transformer ensures mounting on a TS35 rail compliant with EN 50022 through a base welded to the core. Transformers may have several primary and secondary windings, and each winding may have additional voltage tap changers.
