How does APFC panel work?

APFC Panel has microcontroller based programmable controller which switches the capacitor banks of suitable capacity automatically in multiple stages by directly reading the reactive load (RKVA) which works in the principle of VAR sensing tends to maintain the PF to 0.99 Lag.

What is APFC panel?

Automatic Power Factor Control or APFC Panels are mainly used for the improvement of Power Factor. APFC is an automatic power factor control panel which is used to improve the power factor, whenever required, by switching ON and OFF the required capacitor bank units automatically.

How does a power factor panel work?

Power factor (PF) is the ratio of working actual power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). The result is expressed as kVA units. Power Factor defines the ratio of true power used in a circuit to the apparent power delivered to the load circuit.

Is standard for APFC panel?

IEC 61921: (Power Capacitors- Low voltage power factor correction banks) is the international standard applicable for Low Voltage Power Factor Correction Banks and Automatic Power Factor Correction (APFC) equipments intended to be used for power factor correction purposes, equipped with built in switch gears and …

How is APFC calculated?

Suppose Actual P.F is 0.8, Required P.F is 0.98 and Total Load is 516KVA. Power factor = kwh / kvah. kW = kVA x Power Factor. = 516 x 0.8 = 412.8.

What is the use of capacitor panel?

In electric power distribution, capacitor banks are used for power-factor correction. These banks are needed to counteract inductive loading from devices like electric motors and transmission lines, thus making the load appear to be mostly resistive.

What is a power factor panel?

The power factor correction panels are designed to improve the power factor in electrical systems while ensuring energy and cost efficiency. They are suitable for a variety of processing plants with fluctuating loads, such as steel plants, chemical plants, paper mills, and automotive plants.

What is the working principle of a capacitor?

Answer: A capacitor is a device that is used to store charges in an electrical circuit. A capacitor works on the principle that the capacitance of a conductor increases appreciably when an earthed conductor is brought near it. Hence, a capacitor has two plates separated by a distance having equal and opposite charges.

What are the advantages of capacitor?

What is the advantage of a capacitor?

• Capacitors get charged and the energy is accumulated quickly.
• The stored energy is delivered quickly.
• Compared to other devices losses are less.
• Maintenance is less and has a long service life.

How does an APFC panel control power factor?

An APFC is effective as a single-point installation which can be used to control the power factor for a large number of loads, instead of installing capacitors at the individual locations of each load. Depending on the loads in operation, various levels of kVAR compensation are required to maintain proper power factor.

Which is the international standard for APFC panels?

The guidelines for design, installation, operation and safety of APFC panels are followed based on this international standard.

What are the specifications of APFC panel of 200kvar 12 stages?
