We know that the utilization of a device can not be 100% utilization, that is, running at full capacity, the number of equipment is particularly large, so many devices can not run at the same time at the same time, this time in order to calculate the capacity of a certain moment, it is necessary to take into account the need for equipment or utilization factor, such as the peak, the equipment up to half of the work, we take the coefficient 0.5, and then multiplied by kW by the factor 0.5, and then multiplied by kW by the factor 0.5, and then multiplied by kW by kW, and then multiplied by kW by kW by kW. Then multiply the kilowatts by the factor 0.5, the resulting value is commonly known as the calculated load value.
