What is the use of APFC relay?
APFC Relay uses to automate the capacitor bank. One of the most difficult roles in the place where a high and controlled amount of electricity is applied.
What is APFC and how it works?
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.
What is APFC controller?
The (APFC) controllers enable monitoring of key parameters such as power factor, %I-THD & %V-THD to achieve the desired power factor, which results in energy saving and reduction in electricity bills.
Why capacitor is used in APFC?
Why capacitor panel is required? Capacitor Panels are special devices designed as it verily increases the power factor correction by a large magnitude. Normally the electric load running all around a facility or residence is reactive in nature and Capacitor panel can prevent in great losses as mentioned earlier.

What kVAr means?
Kilovolt-amperes reactive
Kilovolt-amperes reactive, thousand Volt-ampere reactive, a unit of reactive power.
What is the full form of APFC?
Active/automatic power factor correction/control (panel), used to control the power factor of electrical loads.
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.
How is APFC rating calculated?
What KVAR means?
What is Rtpfc panel?
Previous. Smart Logic based Real Time PFC (RTPFC) is a direct replacement of the traditional APFC using contactor-based logic with the advantages of smart switching technology. Like an APFC, the primary function of the RT- PFC is reactive compensation.
What is this power factor?
Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A).
What is kVAR vs kVA?
If you want to be particular about the difference between KVA and KVAR, kVA stands for real or actual power while kVAR stands for reactive or inductive power. When you see the energy that creates motion, light, heat, and sound, those are all powered by active power.
Why kVAR is important?
Reactive power (KVAR) required by inductive loads increases the amount of apparent power (KVA) in our distribution system. This increase in reactive and apparent power results in a larger angle θ (measured between KW and KVA).
How is APFC panel connected?
the main application of apfc panel is it has automatic capacitor which connected according to requirement of reactive power . 1. INTRODUCTION: The power factor is the ratio between KW and KVA generated by the electric load, where KWis the active power and KVA is the apparent power.
How is APFC panel size calculated?
= 516 x 0.8 = 412.8. Required capacitor = kW x Multiplying Factor. = (0.8 x 516) x Multiplying Factor. = 412.8 x 0.547 (See Table to find Value according to P.F 0.8 to P.F of 0.98)
Is code for APFC panel?
Apfc panel and HSN Code 85321000 Export from India.
Why capacitor is rated in kVAR?
Capacitor banks designed for power factor correction are rated in kVAr (kilo-volt-ampere reactive) because it’s convenient. One will typically know the reactive power required by some load, then it’s simply a matter of selecting a capacitor of the equal but negative reactive power to improve the power factor.
How does Rtpfc work?
Smart Logic based Real Time PFC (RTPFC) is a direct replacement of the traditional APFC using contactor-based logic with the advantages of smart switching technology. Like an APFC, the primary function of the RT- PFC is reactive compensation. However, the correction is completely, instantaneous, and precise.
What is a KVAR?
Definition: KVAR is the measure of additional reactive current flow which occurs when the voltage and current flow are not perfectly in phase.
What is the full form of KVAR?
1000 Volt Amps Reactive (VAR) = 1 kiloVolt Amps Reactive (kVAR). Usually used to express power in all forms, but is reserved to express real power. 1000 Watts (W) = 1 kiloWatt (kW). Used to express the total load in a circuit. 1000 VA = 1 kVA (kilovolt Amps).
What is the formula for kVAR?
For the KVAR formula, it is as follows: Q = X*I*I. In reactive power formula, X refers to the reactance of the circuit and I is the current that runs through the circuit.
What is kVAR full form?
The unit used for reactive power is volt amps reactive (VAR). Used to express reactive power in a circuit. 1000 Volt Amps Reactive (VAR) = 1 kiloVolt Amps Reactive (kVAR). Usually used to express power in all forms, but is reserved to express real power.
How do you convert kVAR to kVA?
kVAR to kVA Calculation:
A generator is sending 25kVAR reactive power @ 0.95 pf to the load, hence calculate the apparent power of the motor. S(kVA) = 25 / 0.3122499 = 80 kVA. The generator will be running at 80kVA apparent power.
