3 Phase Transformer 3-Phase Dry type 400V/380V-220/208V

3 Phase Transformer 6kva/15kva/600KVA/690KVA 3Phase Dry type Autotransformer 380V-208V, 480-380v, Primary 400 V( star on delta) to Secondary 230V , AC ( delta on star) 50 Hz/60Hz 3 Phase Transformer refers to the transformer with electrical isolation between the input winding and the output winding. The isolation transformer is using to avoid accidentally touching the electrified body at the same time. The isolation of transformer is to isolate the current of the original and secondary side winding coils. The main function of the isolation transformer is to completely insulate the primary side from the secondary side and also isolate the circuit. In addition, by utilizing the high frequency loss of its iron core, high-frequency clutter can be suppressed from entering the control circuit. The use of isolation transformer to make the secondary suspension to the ground can only be using in situations with small power supply range and short lines. At this point, the capacitance current to the ground of the system is not small enough to cause personal injury. Another important role is to protect personal safety! Isolate hazardous voltages. With the continuous development of the power system, transformers play an increasingly important role as key equipment in the power system, and their safe operation directly affects the reliability of the entire power system operation Transformer
