Can adjusting the voltage on the 10KV side of a 10/0.4KV power distribution system reduce electricity consumption?
Thread Content
In a 10/0.4KV power transformation and distribution system, can adjusting the voltage on the 10KV side reduce energy consumption, provided that the electrical load remains unchanged and the voltage on the low-voltage side meets the required standards? For example, if the voltage setting on the 10KV side was originally 10.5KV and it is adjusted to 10KV, can this reduce the total electricity consumption? Incidentally, the meter is on the high-pressure side.
Law of conservation of energy – instead of thinking about these things, it’s better to increase your power output
Many loads are of the \"constant power\" type: as the voltage drops, the current increases, but the power remains unchanged. Reducing the voltage when operating such loads has no effect; in fact, the power may even increase； However, some loads experience an increase in power as the voltage rises, and a decrease in power as the voltage falls; if such loads are the predominant type, there may be a slight decrease.
The electricity consumption is measured in KWh. If the electrical equipment remains unchanged and the power factor COSφ is 1, the only way to reduce electricity usage is by reducing the time of use. Haha, give it a try
Isn’t the power of a three-phase motor given by P=1.732*UI COSφ? If I lower the voltage from 430V to 410V, the power should decrease, right?

:L:'Is that so?
