Most of the commercial and Industrial installations in the country have large electrical loads |
| |
which are
severely inductive in nature, such as motors, large machines, air conditioners, |
| |
drivers etc. Which results in a severely lagging power factor. This means loss and wastage |
| |
of energy and heavy penalties by electricity boards. In case of fixed loads this can be taken |
| |
care by manual switching of capacitors. |
| |
|
| |
However in case of rapidly varying and scattered loads it becomes difficult to maintain a high |
| |
power factor
by manually switching on/off the capacitors in proportion to variation of load |
| |
within an installation. This
drawback is overcome by using an APFC panel (Automatic Power |
| |
Factor Correction Panel) which not only maintains a high power factor but also eliminates the |
| |
eliminates the need for constant manual intervention. |
