Separating transformers, 1TT type for TS35 busbar
Purpose and design
Single-phase separating transformers are designed to supply small electrical appliances when voltage separation is required. 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 or secondary windings. The windings of transformers can provide additional voltage tap changers on the supply and load sides. The connection terminals can be located on one or both sides of the transformer.
