    hi everyone

    i am wanting to know what are the causes and implications of power loss in electronic circuits

    for example due to heavy inductive load etc.

    thanks

    Kind of a broad question. Power loss does imply stoppage of service.

    Back in 1970, VEPCO (Virginia Power & Light) had poor service to the Naval installation at Dam Neck. We lost power with every thunderstorm. This was a daily occurrence in summer. The power loss caused equipment failures in the dozens of computers and peripherals in one building.

    As to causes and inductive loads, the base needed 3 phase 400 Hz power. There were three 100KW motor generators that used 3 phase 480 volt service to make the 120 volt 400Hz the equipment use. One day after a power drop, a lieutenant, anxious to get the day's simulations running again, went from one controller to the next, firing up a three motor generators as quickly as possible. The load of those monsters starting up together caused the power lines to the base to literally melt off the utility poles.

    The causes are certainly more numerous than that, and the implications would seem to be obvious - nothing electrical works.

    Power loss can be described in many different ways. You'll have to be more specific.
    Hah! Good stuff!

    the power loss i am looking for would be in an electrical equipment in an engineering factory.

    how would you make the equipment loss less power

    That is a different problem in the light of your first question, which seemed to ask what effects power loss was on electronic circuits. When you speak of electrical equipment, compensating for power factor would seem to fulfill that requirement.

    Oh, power efficiency. I was thinking about brownouts and blown breakers. Now this sounds like homework. Is it?
