where voltage is transformed from high to low or the reverse using transformers. Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps. A substation that has a step-up transformer increases the voltage while decreasing the current, while a step-down transformer
The next step in determining the correct transformer to use would be some simple multiplication and addition. Once you know the length or amount of product that you will be using. Simply multiply that variable by the products wattage spec and then add an additional 10-15% on top of that in order to not overdrive the power supply. Smaller transformers attached to the bus step the power down to standard line voltage (usually 7,200 volts) for one set of lines, while power leaves in the other direction at the higher voltage of the main transformer. The next time you are driving down the road, you can look at the power lines in a completely different light.
