## Calculation of the energy savings

**In order to calculate power factor correction for your installation, your should follow the steps below:**

**Step 1** **– Calculate Actual Load (kW)**

(Load) Power **kW** = Volts **V** x **√3** x Current **I** x Power factor **Pf**

**Step 2 – Calculate Required Power Factor Correction (kVAr)**

Power Factor Correction **kVAr** = Power **kW** (**TanΦi – TanΦd**)

**Φi** = Cos^{-1} Initial Power Factor Pf

**Φd** = Cos^{-1} Required Power Factor Pf

**Step 3** **– Calculate Actual Power Factor Correction [kAVrl**

Actual Power Factor Correction Pf = Cos (**Tan ^{-1}** (

**TanΦi**–

**Correction kVAr**/

**Power kW**))

Typical Power Factor Correction available in multiples of 25kVAR’s, for further details please Contact Blakley Electrics Technical Department.

**At the end of the spreadsheet you will get the calculation of the energy savings for above power factor correction.**

- Initial Current (Amps)
- Original Load (kVA)
- Corrected Current (Amps)
- Corrected Load (kVA)
- Reduction in Current (Amps)
- Reduction in Load (kVA)
- Annual CO2 Savings ( kg C02)

Hello Friends,

I want to learm Electrical Engineering. Where i start because lot of topics in the electrical. Please guide me.

mail id : alvaajid@gmail.com

bvenu

sir i am working as a technician in private industry, plant is running with load about 900 kva how much capacitance we should need to connect, what kind of problems arise when we are connect capacitance more than required value kindly send the answer to my mail id

thanking you sir.

Domicel

You will spend more capacitors than necessary, I presume thati It is expensive. You will loose money. And if there were a much more capacitance, you will need more KVAr again, but now capacitive.

nirnal kumar

sir, give me formula for improve power factor. how can i get which capacitor will improve power fsctor

eng.saif.

thanks a lot for sharing of important electrical information .I thinks this side is very helpful for EEE ,MEE,

ghasem razeghi

I am an electrical engineer graduated from s.j.c.e mysore – india .

good information i got from your site.

thanks a lot.

Revocatus Mwankemwa

The information I have got are very useful and are of great importance to the problem that I was working on.
