Answer / sourabh vishwakarma

w=va
kw=kva
but differnce is only of power factor if consider unity pf than kw=kva

kw=v*a*pf*1000
kva=v*a*1000

Is This Answer Correct ?    0 Yes 0 No

Describe kW and kva and difference between..

Answer / nidhi sheth

Both are power units. Voltage multiplied by current.
The difference is normally KVA has a power factor following it i.e., it is used in Ac measurements.

KW = Kilo volt * Current
KVA = Kilovolt * Current * power factor
When power factor =1, then KVA = KW

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase), before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
