What does PF mean in electrical?

Contents

Going one step further, Power Factor (PF) is the ratio of working power to apparent power, or the formula PF = kW / kVA. A high PF benefits both the customer and utility, while a low PF indicates poor utilization of electrical power.

What is PF and DF?

Dissipation Factor

With the exception of electrolytic and large power capacitors, most wound dielectric type units utilize a ratio figure known as the “dissipation factor” (OF) instead of the Power Factor (PF). By definition, this DF is the ratio of the equivalent series resistance to the reactance.

What PF stands for in capacitor?

The picofarad (pF) is sometimes colloquially pronounced as “puff” or “pic”, as in “a ten-puff capacitor”. Similarly, “mic” (pronounced “mike”) is sometimes used informally to signify microfarads. Nonstandard abbreviations were and are often used. Farad has been abbreviated “f”, “fd”, and “Fd”.

What is PF in meter?

The power factor is the cosine of the angle between the voltage and current. The power factor meter determines the types of load using on the line, and it also calculates the losses occur on it.

What power factor should I use?

The ideal power factor is unity, or one. Anything less than one means that extra power is required to achieve the actual task at hand. All current flow causes losses both in the supply and distribution system. A load with a power factor of 1.0 results in the most efficient loading of the supply.

What is the opposite of dorsiflexion?

Plantar flexion is the opposite of dorsiflexion and involves moving the foot in a downward direction, toward the ground. … The muscles whose tendons cause plantar flexion are located on the back (posterior) and inside of the leg, and pass into the back of the foot via the ankle joint. These include: tibialis posterior.

How can I change pF to F?

To convert a picofarad measurement to a farad measurement, divide the capacitance by the conversion ratio. The capacitance in farads is equal to the picofarads divided by 1,000,000,000,000.

What is the value of 104 capacitor?

Electronics Components: How to Read Capacitance Values on a Capacitor

Marking Capacitance (pF) Capacitance (ìF)
473 47,000 pF 0.047 ìF
104 100,000 pF 0.1 ìF
224 220,000 pF 0.22 ìF
474 470,000 pF 0.47 ìF

What is PF surcharge?

A Power factor surcharge is imposed when your power factor is less than 0.85. … 1.5% surcharge on the current bill – for every 0.01 less than 0.85 power factor and 3% surcharge on the current bill – for every 0.01 less than 0.75 power factor.

How does a PF meter work?

The basic working principle of power factor meter is similar to that of dynamometer type wattmeter i.e. when the field produced by moving system tries to come in line with the field produced by the fixed coil, deflecting torque is exerted on the moving system which deflects the pointer attached to it (the moving system …

What is PF rebate in electricity bill?

b) Power factor rebate is considered as per the tariff i.e. if the average power factor of the consumer’s installation in any month is above 95%, the consumer is entitled to a rebate at the rate of 0.5% (half percent) in excess of 95% power factor on the total amount of electricity bill for that month under the head “ …

How is PF calculated on electricity bill?

Power factor (PF) is the ratio of useful current to total current. It is also the ratio of useful power expressed in kilowatts (KW) to total power expressed in kilowatt-amperes (KVA). … Example: 60 KWk PF = 0.60 = 60% =100 KVA Kilowatts = 60 KW, KVA = 100 KVA.

How do I know if my PF is leading or lagging?

If the currents leads the voltage (greater angle than voltage) then the power factor is leading (capacitive load). If the current lags the voltage (less angle than voltage) then the power factor is lagging (inductive load).

What is a bad power factor?

Good power factor is generally between 1.0 and 0.95. Poor power factor is anything from 0.95 and 0.85. Bad power factor is anything below 0.85. Commercial office buildings are usually somewhere between 0.98 and 0.92, industrial buildings could be as low as 0.7.
