Not all the loads in an electrical installation operate at their nominal power all the time. A good example are the plug sockets which are rarely used at their maximum output (which in this case would be the limit of the protective fuse of 10 or 16 amps). So, in order to get a realistic image of the power demand, there is also a simultaneity factor applied. But each tipe of consumer can have its own factor depending on the tipe of load, ratio of its usage and also on the interpretation of the engineer. Coming back to the example with sockets, usually a coefficient of 0.2 is taken into consideration but for other loads that are operating at their nominal current/power(like lighting) a higher factor up until 1 would be assumed.
By multiplying the nominal power with simultaneity factor you will get the power demand.

Why low power factor need surcharge?
Low power factor leads to higher current in the system for the same real power requirement. (Check out the power triangle in any basic electical engg. book) higher current leads to higher system losses for the supply & distribution companies, drop in voltage, also necessiates higher sizing of system components. Hence low power factor attracts penalty also on the other hand some distribution companies provides incentives for maintaining higher pf. Regards, Sameer Shaikh
What is the difference between primary electrical distribution and secondary distribution?
Primary electrical distribution carries medium voltage power to distribution transformers near the customers. Secondary electrical distribution transfers the power from the transformer to the households.
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
What is relation between power factor and phase sequence?
The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power,[1][2] and is a number between 0 and 1 (frequently expressed as a percentage, e.g. 0.5 pf = 50% pf). Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power can be greater than the real power.In an electric power system, a load with low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment. Because of the costs of larger equipment and wasted energy, electrical utilities will usually charge a higher cost to industrial or commercial customers where there is a low power factor.Linear loads with low power factor (such as induction motors) can be corrected with a passive network of capacitors or inductors. Non-linear loads, such as rectifiers, distort the current drawn from the system. In such cases, active or passive power factor correction may be used to counteract the distortion and raise power factor. The devices for correction of power factor may be at a central substation, or spread out over a distribution system, or built into power-consuming equipment.
What are the advantages and disadvantages of unity power factor?
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.
How many syllable does simultaneity have?
it has 5
Is Poor power factor causes overload on alternator transformer and distribution lines?
yes it is true gal or boy what everAnother AnswerPoor power factor doesn't necessarily cause an 'overload' (transmission/distribution systems are designed to cope), but it is certainly responsible for a load drawing more current than necessary. This is because a load with a poor (low) power factor draws more current than is necessary to supply the same amount of energy.
What is lane distribution factor?
DL = lane distribution factor, expressed as a ratio, accounts for the distribution of loads when two or more lanes are available in one direction
Definition of distribution of power?
The power distribution is a continuous distribution with a parameter that we will denote k.
What is a real life application of the square root function?
Electrical engineers use it in calculating power factor and electrical load distribution when dealing with 3 phase power connections.

Why unity power factor is used in load test?
When power factor is at unity, the voltage and current waves are aligned or in phase with one another. Since power is the product of voltage and current, power transfer is maximized at unity power factor. When power is transmitted at a lower power factor, greater current is required to deliver the same amount of power. When current is increased, the size of the transmission, distribution and generation systems, all have to be increased accordingly, along with the price of the killowatt-hour at the meter.
What is the key factor in describing population distribution?
The key factor in describing population distribution is the land resources available. This is what will determine the population density of a place.
An environmental factor that prevents an organism or population from reaching its full potential of distribution or activity?
The factor that prevents an organism or population from reaching its full potential of distribution or activity is called the limiting factor.
What is APFC panel?
An Automatic Power Factor Correction (Controller) panel is used to Save Energy by consistently maintaining higher power factor. Low Power Factor leads to poor power efficiency, thereby increasing the apparent power drawn from the distribution network. This results in overloading of Transformer, Bus bars, Switch gears, Cables and other distribution devices within the Industry or consumer area.With an APFC the energy producer can:Avoid Penalization for lower power factor.Enjoy incentives for higher power factor operation being extended to Industries by some Electricity Boards/ Companies.Optimize the connected load for improved plant load factor.Avoid manual disruption.Avoid high current consumption losses.Improvement in voltage regulation.Decrease Maximum Demand KVA, thus avoiding penalty and Demand Charges.
