The main characteristics of the generators include:
– power;
– automation;
– type and type of generator;
– single -phase or three -phase.
One of the most important characteristics of the generators is their power. More powerful generators are more expensive than low power unit. In everyday life, 4 kW gas generators are most often used, the capacities of which will be enough for a small house. For a suburban cottage where a whole family lives, a power plant with a capacity of up to 30 kilowatts is suitable. To connect concrete mixers, grinder or drills during the construction of the house, it will be enough to use a 6 kW generator with a power generator.
In order to correctly calculate the required power of the generator, you need to find out the total power of all electrical devices that will be connected to this unit. In this case, you also need to take into account the reactive and active loads on it.
Active loads are those loads where all energy is spent on the heat of consumers (hair dryers, heaters, electric stoves, incandescent lamps, irons). The reactive loads are loads in which energy is spent on the creation of electromagnetic fields, and turns into thermal energy. Electromagnetic fields are needed in electric motors (drills, pumps, refrigerators, vacuum cleaners).
During the calculation of the load on the generator, it is also necessary to take into account the reactive loads, because the starting current during the inclusion of consumers increases about three times. So that the unit does not turn off during reactive loads, they must be taken into account when choosing a generator. You can calculate the exact power of this equipment using special formulas, however, it will be more reasonable and profitable to seek help from specialists who will calculate the total power of electrical appliances, and will also help choose the best generator for your purpose.
When choosing a generator, you need to take into account the type of engine. Engines are gas, diesel and gasoline. The most popular in our country are gasoline generators that are easy to operate, effective and economical. As you know, gasoline in our country is inexpensive, which, of course, affects the payback period of the unit and the cost of its use.
