Power Factor Control
- In the great majority of cases, poor power factor is due to inductive loads which can be compensated by adding electrical devices called capacitors into the circuit.
- PFC techniques aim to bring the power factor closer to unity by reducing the effects of reactive power.
- Reactive power charges can be eliminated to provide instant savings.
- Power factor (PF) is measured between 0 and 1.0 (usually given as a percentage, with 100 percent or 1.0 being unity).
- Widely used in the electrical applications, these are easy to install, environment friendly and require low maintenance.
- These automatic power factor control relays are used to maintain power factor of system, automatically by switching the capacitor banks as per the needs of the system
