Is it true online ups having bypass mode if it is true then why we called ups because it is interrupting power when goes in bypass mode
Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.

I don't understand why when we connect high voltage source in DC to electronic motor , we must add capacitor and resistor in parallel ? (I know that we use capacitor because we want to absorb the current that in the first second electronic motor in opposed with current course produce. ) what are the feature of Resistor and in such situation ?
