The purpose of changing these levels include reducing AC Voltage from 220VAC to 12 VAC or increasing Voltage from 110VAC to 220 VAC. Transformer or transformer works based on the principle of Electromagnetic Induction and can only work on alternating voltage (AC). The transformer (transformer) plays a very important role in the distribution of electric power. The transformer raises electricity from the PLN power plant to hundreds of kilo Volts to be distributed, and then the other transformer reduces the voltage to the voltage needed by every household or office that generally uses 220Volt AC Voltage. Environmental temperature is the temperature of the environment or environment which is influenced by several factors and can change based on the weather in the area. Loss of life is a condition in which an equipment or component has an age value that is less than the age that should be determined due to various factors} }
