Is a 125 kVA transformer safe?

125kVA is only a common high-voltage level for high voltage, under this voltage level or safety distance, there will be no major problems, such as corona, leakage or arc phenomenon, you still need to pay attention to special circumstances, such as storms such as rainy days, because the transformer is grounded after installation and operation, which is based on discharge. In rainy weather, it is important to advise you and your family to stay away from the transformer.

As far as living is concerned, according to my more than 30 years of experience in the high-voltage industry, if there is a wall as an insulating medium, it is harmless to humans and animals.

125kva is the capacity of the transformer, what is the voltage level?

Assuming that it is a conventional voltage level of 10kV, the insulation distance in the air is 250mm according to the relevant national standards

But if the hand can touch the live part without the help of a tool, this should not be allowed.

As for radiation, the radiation of ordinary distribution transformers is very small, and the grounded metal housing can shield most of the electromagnetic radiation.

Use the radio to see if there is any interference, if there is a magnetoelectric field interference from the transformer. There is no conclusive jury about how much harm it does to the human body in the long term.

If your building is not illegal, go to court and sue him. This is equivalent to putting a ticking time bomb at home.

The drag load capacity of the transformer mainly depends on the power factor of the load it is dragging, and its formula is calculated as: p=s*cos

Among them: 1. p is the active power, which is the rated power of the load;

2. S is the apparent power, which is the total power that the transformer (power supply) can provide, which includes both active power and reactive power;

3. COS is the power factor.

It can be seen that if cos = 1, then, p = 125 * 1 = 125kw, that is, the maximum load power that a 125kva transformer can drag is 125kw; But in reality, it is difficult for COS to reach 1, and the economic operation efficiency of the transformer is: , generally according to the value, that is, p=125*, that is to say, it is better to drag the 125kva transformer.

It has to do with your power factor, the higher the power factor, the more power you can have, otherwise the smaller. Let's say you have a power factor of 125 kilowatts.

Of course, it's better to have 125 kilowatts. It can exceed 20% in a short time. It also depends on the load quality (that is, the reactive power should be as small as possible).

Power factor) = 100kw. The load power factor is different, and the power of the electrical appliances with it is different.

The payload series has already taken into account the issue of start-up.
