1. The unit of apparent power is KVA, and we usually use it to express transformers and UPS (Uninterruptable Power Supply) in China. And its basic function is: the capacity will uninterruptedly supply power when mains supply is interrupted.
2. Active power is 0.8 times apparent power, and its unit is KW, such as 80KW is 100KVA. It is used for power generation equipment and electrical equipment in China.
3. The rated power of the diesel generator set is the power that can be continuously operated for 12 hours.
4. The maximum power is 1.1 times the rated power, but it can be only used for an hour within 12 hours.
5. Economic power is 0.75 times the rated power, which is the output power of diesel generator sets that are not limited by the long-term operation. In the operation of economic power, the fuel consumes least, and failure rate is lowest.
