Benefits of power factor correction

13/05/2011 by 3 Comments

Now around the world,hot topic is about energy saving and energy efficiency.The main item very popular for discussion is how to reduce electricity bills.

In industrial sector,the first step to reduce electricity bills is a power factor correction.This post i explain about the benefits of power factor correction for energy saving and efficiency.It also common practice for industrial.

I already discuss in my last post about power factor correction and capacitor sizing for power factor correction.If you understand the concept and how to calculated the capacitor sizing,you also can do it your self for power factor improvement. read more

Power factor correction

08/05/2011 by 5 Comments

As with any electrical equipment,the works of efficiency usually determine from poor to excellent.How we measure the electrical efficiency?The answer is power factor.I discussed about how to sizing capacitor for  power factor correction on my last post.

Most of electrical motor or inductive equipment powered by two types of power.First is a working power.It measure in kilo watt (kW) unit.It mean this power is actually used to operated the electrical equipment.

Second is a reactive power.It mean inductive equipment need this power to  produced the necessary flux for the operation.The measurement is the kilovar ( kVAR ) unit.

So the working power (kW) and reactive power (kVAR) combined together to make up apparent power.It measure in kilo volt ampere (KVAR) unit.That is we call power factor correction. read more

Air-conditioner sizing

17/04/2011 by 13 Comments

Air-conditioner is one of equipment that used and  popular in around the world to cooling our room,office or any space.Now in our market,air-conditioner have in many types and sizes.It depend on our application and types of space that we want use it.

When install an air-conditioner,we want it running in more efficiency and enough capacity can cooling the room.So we must install the right size for our room to ensure it suitable with room size and our application.

If we choose a smaller size for air-conditioner,it will running all the times to cooling the room.Your electricity bills will increase.But if you choose too big,it can kill you also with high electricity cost.So we need to choose a right size for air-conditioner. read more
