Understanding APFC Relay: Working Principles in Electrical Systems
In the maze of electrical systems, APFC panels are considered one of the crucial devices that are applied in managing the power factor requirement. Any electrical system could not perform its operations without a sufficient power factor. To summarise, APFC is an electrical component that enhances power with certain capacitors' help. In this blog, we will discuss every detail related to APFC.
What is an APFC relay?
The fundamental objective of an APFC relay is to cope with the power factor of an electrical system efficiently. The power factor is a ratio between real and apparent power. Besides reducing electricity consumption, it also indicates how effectively the electricity is used for various equipment. APFC relays are in charge of managing the power factor with the aid of a correction capacitor.
What is the purpose of the APFC relay?
Other than measuring the power factor, here are some other purposes of an APFC relay, and they are as follows:
1. Ensuring a stabilised system: By managing the power factor, the stability and reliability of an electrical system improves, which ultimately increases the equipment’s lifespan.
2. Automatic: The entire work of an APFC relay is performed automatically with the help of a capacitor. Hence, reducing the involvement of any kind of labour work.
3. Power factor: The fundamental objective of an APFC relay is to monitor the power factor at a desired level. This ensures that the electrical system can efficiently perform its operations.
4. Efficiency of the electrical equipment: At a high power factor, the operations of any electrical device can be managed efficiently as it reduces heat production and frequent voltage imbalance.
5. Reduction in electricity bills: Not only does an APFC relay improve the lifespan of any electrical equipment, but it also reduces electricity consumption, further generating low electricity bills.
What is APFC relay full-form?
APFC stands for Automatic Power Factor Correction, and is a vital component in the electrical system for optimising electricity consumption by enhancing the power factor.
Why use APFC panels?
Some of the benefits of using an APFC panel are given below:
1. Control of operations: The APFC panel benefits operators by providing them control over the functions of the panel from a certain location.
2. Minimised cost: Low energy consumption can be reduced by maintaining a high power factor. The APFC panel must maintain the power factor at an optimum level.
3. Prevention of damage: If the power factor is maintained at a low level, then it can result in overheating, which can destroy the internal components of an electrical system. APFC panels can be used as a prevention measure to reduce the risk of any damage.
4. Monitoring: Besides providing control to the operator, APFC panels are equipped with monitoring capabilities to check the consumption level, power factor levels, and many more.
5. Boosting the power factor: The fundamental job of any APFC panel is to enhance the level of the power factor and check whether it is close to the level of unity. It effectively reduces consumption costs and improves the lifespan of any equipment.
What does power factor mean?
The power factor is the simple ratio between the power that has been consumed and the total power required to run any electrical equipment. This ratio measures whether electrical equipment can efficiently consume electrical power.
Ideally, the unit of the power factor should be close to 1, but due to the presence of various constraints in the real world, the unit could be less than 1. Being less than 1 does not indicate that the electricity has been consumed efficiently. Rather, it may indicate complicated problems in the future.
Hence, to avoid such unintended accidents, APFC relays are installed to ensure that the electricity is properly consumed without any waste.
What are automatic power factor control relays?
The automatic power factor control relay is installed in electrical equipment to control the flow of electricity. They are also identified as an effective correction measure to prevent power wastage. The main purpose of an automatic power control relay is to monitor the level of power factor that remains within the range of 1. In the present world, it is considered to be one of the greatest electrical components for an even distribution of power.

For various electrical products, Lauritz Knudsen (Formerly L&T Switchgear) is your ultimate destination. There is a wide range of APFC relays that are manufactured to serve its purpose commercial as well as industrial electrical components. The APFC relays are known to effectively correct power wastage leading to the ultimate reduction in the cost of energy consumption.
The highlight of the APFC relays is the etaULTRA controller. They can sense any imbalance in the power distribution and accordingly provide automatic adjustment of the capacitors. Interestingly, the etaULTRA controller is pre-installed with a program that enables the APFC controller to maintain an accurate power factor level.
