What are demand factor and load factor of transmission and distribution?
Sumithraebenezer
The load factor of transmission and distribution takes the average load divides it by the peak load in a specific time frame. The demand factor is defined as the ratio of the maximum demand in a system in regard to the total connected load in the system.

How can calculate maximum demand load?
maximum demand load can be calculated as: # maximum demand=demand factor * Connected load or by # maximum demand = connected load * Diversity Factor Note: Demand factor and diversity factor are NOT same
How improve load factor?
Ratio of Average load to Maximum demand for a given period (for a day, month or year) is termed as Load factor or Plant Load Factor (PLF). Load Factor = Avg. Load*24/Max Demand*24 ......... For a Day. This Load factor is very important in the sense of calculating the overall generation cost. It is always less than 1. Higher the LOAD FACTOR of a power station,lesser the overall per unit generation cost of the power station.
What is the importance of load factor in power system planning?
load factor is the ratio of average load to max demand for a given period.High load factor meansless cost per KWHmore efficient use of power plant
What is the effect of load factor and diversity factor on cost of generation in a power station?
Load factor effects the cost of generation. Higher the load factor higher will be the average load. So no. of units generated for a given period of time for the same max. demand will be more. Therefore, overall cost per unit of electrical energy decreases due to distribution of standing charges which are proportional to the max. demand and independent of units generated. Diversity factor effects the cost of generation. More is the diversity lesser will be max. demand due to which installation capacity of plant will be less. Lesser is the installation capacity lesser will be the capital required for installation. So lesser will be generation cost. And the fixed charges in the tariff would be less.
What is the diversity factor of full load transformer?
Diversity factor is the ratio between sum of each individual maximum demand and the total maximum demand. There are several equipment with different connected load and its maximum demand in an industry. Each equipment maximum demand could be different and might occur at different times. A well estimated or measured diversity factor would tell as to what percentage of total maximum load would actually occur. Diversity factor is always less than 1. Diversity factor has to be obtained either by measuring the actual sum of each individual load and maximum demand or estimated and has relation to the transformer full load .
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 the meaning of 'plant load factor'?
"Load Factor" is an indicator of how steady an electrical load is over time. If your electric billing rate includes both an Energy (kWh) and Demand (kW) charge, your load factor can be calculated by the following formula: L.F. (percent) = [(Total kWh)/(# Days in Bill Cycle x 24 hrs/day)]/[Peak kW Demand] If your load factor is low, you should look for ways to even out your electrical usage (i.e., shift energy intensive processes to periods of otherwise low usage). By increasing load factor, you will reduce the impact of monthly demand (kW) charges on your bill. Another way of looking at load factor is: LF = average demand / peak demand for a given period of time. Load factor is the total energy consumed in a period (kWh) over maximum power that can be delivered(kW) in to no of hours (h) in that period. Load factor = Energy consumed (kWh)/ max power (kW) x No. of hours (h)
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.
Define load shedding?
Load shredding is the shutdown of certain parts of an electric grid when the distribution system receives more demand than the current supply. The procedure prevents a complete system failure due to repeat demand.
What is maximum demand indicator?
An electricity board will be fixed some amount of load for consumer (industry or commercial) as per consumers requirement.That is maximum load or maximum demandAnswerA 'maximum demand indicator' (also called a 'thermal demand indicator') is a thermally-operated measuring instrument which indicates the maximum current supplied by a distribution transformer, from which that transformer's actual (rather than anticipated) maximum load can be determined. A distribution transformer is sized based on an anticipated load, resulting from an analysis of the loads to be supplied (taking into account after-diversity maximum demand), this instrument allows the actual maximum load to be compared with that calculated load, and this value should be less if the original analysis was performed correctly.
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.
What causes low power factor?
Reactive power flow results in a lower power factor. In transmission systems, this can be due to unequal source voltages. In load networks, this is usually due to motor load.
