The demand load is the maximum load that is running during a specific period of time.Īs we know that all connected appliances never runs at a same time so we use diversity factor of 80% to get demand load. S.NoĪfter calculation of connected load, We have to calculate demand load. But before this 3 phase load calculation, we need to know the consumption of the each load which will be fed. Using above mentioned formula you can do three phase electrical load calculation. Here, P stands for Power, while V for Voltage, I for Current and P.F is used for Power Factor. For three phase system we use following 3 Phase power calculation formula. Any electrical load which is more than 5KW, we need to have 3-Phase load for it. In previous article, we have performed single phase electrical load calculations. How to do 3-Phase Electrical load Calculation?
