It converts watts into kilowatts because we usually prefer to deal with kW instead of W.īecause we need to use the power factor to calculate the kW from amps, this formula is also known as the ‘3-phase power factor formula’.
The value of the power in the primary is the same as the power in the secondary, as in the case of a transformer.It’s quite easy to convert kW to amps and amps to kW in a simple 1-phase AC circuit (compared to a 3-phase power calculation). The power of an electric circuit is calculated by multiplying the voltage by the current intensity. Based on the phenomena of electromagnetic induction, it is a device that transforms alternating electrical energy of one voltage level into alternating electrical energy of another voltage level. There is a small percentage of losses in real machinery. In the case of a perfect transformer, the power entering the equipment is equal to the power received at the output. Step up and step down transformers are the two types of transformers provided.Ī transformer is an electrical device that allows us to maintain power when increasing or decreasing the voltage in an alternating current electrical circuit. A good-condition transformer is made up of two windings, the main and secondary windings. It's known as a voltage converter because it can convert high voltage to low voltage and vice versa. Electromagnetic induction is used to do this. The transformer converts electrical energy from one circuit to another.
