Typically, generator sets have a main power supply, a backup power supply and a continuous operating power supply. If the main power of a 250 kW diesel generator set is 250 kW, its backup power is 1.1 times, or 275 kW. Its continuous working time can be 24 hours, but the output power can be selected to be about 0.7-0.8 times of the main power. It is 175kw-200kw. Huali Electrical and Mechanical here reminds you that some manufacturers refer to the backup power as unity power, which is confusing and cannot reach the output power.
The 250kw generator can power three-phase multi-phase generators
The 250kw generator can power KTV hotels. Since the power demand of KTV hotels is relatively small, its power loads mainly include audio equipment, electronics, etc.lighting equipment, air conditioning equipment, etc., and a 250 kilowatt generator can meet the electrical needs of these equipment. In addition, if the KTV hotel is in peak period or when the power demand is large, the generator can provide additional power to ensure the normal operation of the equipment. In summary, a 250 kilowatt generator can meet the power needs of the KTV hotel and ensure the normal operation of its equipment.
The maximum output current is approximately 250×1,445≈361A. The rated current of the 250kvA transformer is 360A, which means it can produce 360A three-phase current.
The formula for calculating the rated current of the transformer is as follows: rated input current: capacity/√3/input voltage/efficiency, rated output current: capacity/√3/voltage of exit. For example: 10KV/0.4KV 200KVA oil infiltration transformer with a rendent of 0.95 has a maximum current rating of 12A on the high voltage side and a maximum current rating of 288A on the low voltage side.
A 250 kilowatt generator has a maximum power supply of approximately 420 A.
