A Power transformer is an electronic device designed to alternate current system. It is used to Power transfer electrical energy from one circuit to another with an alternation in voltage. It works on a very simple fact about electricity and helps you constantly regulate the voltage. It is an important device for electric distribution grid, as it can increase the voltage of the electricity and lower the line losses and become fit to be used at safe voltages.
More importantly, a Power transformer responds to fluctuations within power grid by instantly acting as voltage regulators. It directly reduces energy consumption and makes sure the optimized voltage is undisturbed.
