this paper is full of errors, to wit:1) Reactive power is returned to the electric grid as the windings de-energize - the author obviously doesnt know the subject being discussed2) When reactive power supply lower voltage, as voltage drops current must increase to maintain power supplied, causing system to consume more reactive power and the voltage drops further again, the author doesnt know the subject. 3) If voltage reduction continues, these will cause additional elements to trip, leading further reduction in voltage and loss of the load. same as (1)masyado pang maraming errors which makes this document not worth reading
ako author neto , joke, hehehehe. kakatamad magbasa, mamaya basahin ko para mapagaralan din.
sir meron po ba kayong link na tama... or meron kayong mas magandang detailed na explanation?
kung ganon mali pala yun nag-seminar sa amin King Fahd University of Petroleum and Minerals. Dr. Yasre Ahmed Bin Abdul Aziz Ph.D. Degree in Electrical Engineering (EE) from University of Central Florida
may point din naman yung sinasabi ng author kaya lang we need to verify muna kasi mahirap din maniwala agad agad napansin ko lang kasi sa mga power transformer,rating nya lagi nasa apparent power(kVA) saka yung capacitor banks naman nasa reactive power(KVAR) naman yung ratings,baka sa stress may effect yung reactive power kaya importante yung reactive power.
di ba yung reactive power yun ba yung useless power?di talaga magagamit ito dahil wala syang use,better to concentrate na lang yung author sa nearly unity power factor.sana ganito nalang ginawa nyang study:1. ano ang power factor? - power factor is just the ratio between real power (W) and true power (VA)2. ano ang advantages ng mataas na power factor at paano maachieve ito? - if a load has a high pf, there is less need for generators to produce them. 3. mga technique to correct power factor. - adding capacitors to inductive loads (like motors) will reduce the VAR needs of the motor and increase the overall pf of a place. placing capacitors on the main circuit will increase the overall pf of that place4. bakit sa industrial power systems kailangan ng power factor. - industrial facilities tend to have a lot of motors which consume a lot of VARs. in residential places, the total var consumption is small and being taken care of by the utility. which is why industrial places have meters for VARs while residential places only have meters for W5. bakit sa residential di tayo sinisingil sa apparent power(true or active power lang tayo sinisingil) at sa industrial lang nakaimplement?
