Generators have two power ratings - the nominal or principal and maximum rezervnaya.Nominalnaya or generator power is always less than the maximum value, and it is within the power plant can operate without interruption plenty of time. Operation of the generator at maximum power is limited by vremeni.Ne desirable to allow the work of power in this mode for more than 30 minutes - otherwise it will lead to overheating of the unit and rapid engine wear. When you start to take into account the power of the consumers that are connected to the generator odnovremenno.Summarnaya power of all connected loads must not exceed the capacity of the main power plant, otherwise the generator or will not start or will come to order. Also, when calculating the capacity of consumers, you need to take into account the type nagruzki.Esli this electric motors or transformers, then it is necessary to take into account their reactive power (this is the power that the device during start-up of several times its rated capacity.) Therefore, for such loads is better to choose generator with a margin moschnosti.Obychnye consumers (household appliances), have only the active power and do not require starting currents, so the calculation of the total power does not require any additional parameters.
