Capacitor Size Calculator for Power Factor improvement (XLS)

Download free capacitor size calculator for motors and other equipment to improve the power factor. This excel sheet will help you sizing the capacitor bank for power factor correction. The excel program contains the formulas for obtaining the capacitance of the capacitor and also the number of capacitors.

What is The Capacitor?

It is an electronic component whose primary function is charging and unloading electrical charges, and is also used to separate AC ac from DC current when we use it as a filter or filter for unwanted electrical compatibilities, as well as in time circles that depend on the charging and discharge period and have many other uses, the most important of which is the use of condenser in filters and electronic filters and there is a very important use when we use the capacitor to improve the power plants of the power grids, which reduce the value of the actual response capacity in the grid, which is considered to be able to exhaust the network and increase losses.

Capacitor measurement: its symbol (C) and its unit measuring Farad (F) 

We mostly use: (μf, nf, pf) because the value of the farad is very large so we express it in smaller values, such as micro farad, nano farad, pico farad recently developed capacitors with large capacitors of several decimal parts of farad called super Capacitors.

Capacitor Size Calculator for Power Factor improvement

What is the power factor and how to improve it?
Power factor is defined as the ratio of effective capacity (P) consumed by load to total virtual capacity (S) in the circular. It is expressed either as a decimal value, for example 0.97, or as a percentage:97%. The ideal power coefficient is equal to 1 and is called unity. This occurs when there is no ineffective capability in the circuit, so the apparent capacity is equal to effective.
