About Voltage and Potential Transformers
Voltage transformers and potential transformers are used to measure voltage in electric circuits. Their main role is to condition (step down) the voltage to be measured to levels suitable for the measuring instrument. Voltage and potential transformers have a secondary voltage that is substantially proportional to the primary voltage, but differs in phase by an angle that is approximately zero for an appropriate direction of the connections. A low voltage transformer converts normal line voltage (120 VAC) to low voltage (typically 12 VAC). This lower voltage can then be used to power an incandescent low-voltage lamp. A dimmer is specifically designed for an electronic low-voltage transformer. A low voltage lighting transformer converts 120-volt currents to a relatively safe and energy efficient 12-volt (low-voltage) current for many outdoor lighting applications.
