A High Voltage Arc Distribution Transformer (20KV 1A) is an electrical device designed to step down high voltage from power lines to lower voltages suitable for use in various applications. This specific transformer operates at an input voltage of 20,000 volts (20KV) and can handle a current of up to 1 ampere. It is commonly used in power distribution systems to ensure safe and efficient delivery of electricity to residential, commercial, and industrial users. The transformer also helps in protecting electrical equipment by providing stable voltage levels and isolating different sections of the power grid.
