ඔය ups,generators,transformerswala KVA,VA walin ne power eka denne.ethakota apita ona karanne wattage ekane.wattage kiyanne active power ekakne.ethakota oya supplies wala reactive power eka useless power ekakda?ape load eke reactive loadswalata power eka one nadda?meka poddak pahadili karapanko

1 .ethakota oya supplies wala
reactive power eka useless power ekakda?

True power eka 1000W .Reactive power eka 300W kiyala hithamu.. dan me equipment eka wisin 1300W pramanayak thamange source eken illanawa..

e demand eka dennama one source eken ..nathnam equipment eke True power eka, efficiency eka, Torque eka, HP gana ho
whatever magula labenne na..

habai me siyalla diha balan inna CEB meter eka 1300W walata bill krnawa.. 300W
walata nikarune mudal gewanawa, 1000W wenuwata 1300W yawanna hi SWG wires , Transformers one wenawa.. padu keepayai..

nadda?

Quite simply the Watts is the real power drawn by the equipment, while volt-amps is called apparent power.
The ratio of Watts to VA is known as the power factor

If the load is resistive then Watt and VA are the same.
Only for these loads the Power = Volts x Amps equation applies.

For motors.transformers, UPS etc the above equation does NOT apply and the power factor comes into play.

01. machan gewal wala meter eke thiyenne kwh
ne?


natha.. menna me nisai boho aya mislead wenne.. Kwh kiyala
gahala thibbata meken aththatama measure wennne Apparent Power ekai..
True power manina watt meters saralawa, adu wiyadamin issara hadanna bari wela thiyenawa..
( ada kale nm 300Rs yaddi puluwan .. CEB eken

But e meter eka 21,000 withara wenawa hode.. not 300Rs...





02. ethakota manenne kw ne bn.ethakota eka

03. reactive power
eka maninna wenama meter ekak thiyenawanee?

ow .. Electronically nam lesiyen puluwan.. Electrically kranawa tikak wada wadi..
