Step Up Power Distribution transformer
Step up Power Distribution transformer Description
Step-up Power Distribution transformer increases the input voltage and delivers it to the load, and a step-down transformer decreases the input voltage at the load. High voltage is required for efficient power transmission, but the power must be utilized by consumers at a lower voltage for safety reasons. The transition from low voltage to high for transmission requires a step-up transformer. In some countries, step-up transformers are invaluable. For example, the power generation level in India is 11kv; hence, step-up transformers are required at the generating stations. In short, a step-up transformer raises the voltage for transmission purposes.
