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.
What is Horizontal distribution of power?
Distribution of power among different organs of the government is known as horizontal distribution of power. It allows different organs of government, which are placed at the same level to exercise different powers.
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
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
Definition of distribution of power?
The power distribution is a continuous distribution with a parameter that we will denote k.
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
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 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.

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.
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.
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.
Which abiotic factor limits the distribution of the ocean but does not usually limit the distribution of life on land?
water
What is Load Distribution Factor in Electricity Distribution?
distribution factor ['dis·trə′byü·shən 'fak·tər](nucleonics) A term used to express the modification of the effect of radiation in a biological system attributable to the nonuniform distribution of an internally deposited isotope, such as radium's being concentrated in bones.
