Product overview:
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 need for constant manual intervention.
Advantages:
- Economical with faster payback periods.
- Ability to maintain a constant high power factor.
- Eliminates low power factor penalties levied by EB.
- Reduces the KVA demand charges.
- Improves efficiency of the system by reducing losses.
- Prevents leading power factor in the installation during low load conditions
There are various parameters on which these APFC Works:
- Current - Sensing based APFC
- Power Factor Sensing based APFC (It is the mostly used type of APFC Panel)
- KVAR Sensing based APFC
Types of APFC Panels
- Contactor based APFC’S
- Thyristor Based APFC
Structural Design of an APFC Panel
- Cabinet of sheet metal duly powder coated.
- Main incoming switch fuse or circuit breaker for the bank.
- Capacitor bank bus bar.
- Capacitor bank CT's.
- Ammeter selector switch.
- Ammeter for bank current.
