    Compared to brush alternator, brushless alternator is  best because voltage difference in the stator due improper brush contact in slip-ring units cause more unbalance during loading of generator.

    Brushless Alternator: In brushless alternator armature winding as a stator and field winding as a rotor. by this arrangement slip rings are not required to collect induced voltage because the armature part is a stationary one.

  • DC Circuit in AC MCB

    Does using a AC MCB in a DC circuit affect the tripping time or the perfromance?

    Yes defenitly affect the tripping perfomence of MCB (AC) because DC has uni directional flow , the contact area of the contacts in DC MCBs is in higher ratings. There are chances of welding of contacts may also happened in some occasitions.

  • For a 100kw generator, only 50kw of load is connected. Will the generator generate only 50kw or 100kw? If it generate 100kw what happens to rest of the 50kw. What happens if we connect more than 100kw of load?

    100 kw is the full load rating of the generator..... ..that means it can supply 100 kw without exceeding in specified temperature limits .that doesnt mean that it wont be able to supply a load more than 100 kw,it can but not for a longer period of time.after sometime the generator will burn out.if a load of 50 kw is connected to generator the generator will generate only 50 kw& not more than that.the generator will generate power only according to the requirement.

    The Generator produce the power is exactly what we withdraw as load. 100 kw genset can produce 1 kw to 115kw power depending upon the connected/withdrawing load. Normally the generator can produce 115% of designed rating.
