What are the advantage of improving power factor on the part supply authority?

Leading power factor has no advantage as the apparent power will be greater than true or active power...
So power factor should be as close to unity as possible...
Lagging p.f. causes high currents in line, whereas leading p.f. causes over-voltages.

∙ 11y agoLow power factors result in heavier load currents than necessary for any given load. So power-factor improvement as all about reducing the load current for a given load. This reduces the volume of copper required by the supply cables, switchgear, Transformers, etc., thus saving money, and reducing energy losses and voltage drops along the supply lines. Power-factor improvement only applies to industrial and large commercial loads, and is irrelevant to residential consumers.

Does raising the power factor of a residence result in dollar savings on your electric bill?
No. Your energy meter monitors the supply voltage and the in-phase component of the load current, so improving your power factor will have no effect on your energy consumption and, therefore, your electricity bill.
An improvement in technology is a factor that influences?
supply
What are advantages of regulated power supply?
Advantage of regulated power supply.
Why electrical supply are multiple of 11kv?
It is due to presence of form factor(Kf) in the emf equation of Alternators and transformers. Value of form factor is 1.11.
Why can a reactive power load drop the voltage more than the active power load in a transmission line?
A load with a poor power factor draws extra current from the power supply, meaning that there will be more of a voltage-drop in the supply. As an example, if the load is 6 kW on a 240 v supply, the current drawn is 25 amps if the load has a power factor of 1. The kVA is equal to the kW. But if the load has a power factor of 0.8 it needs to draw 7.5 kVA for a power of 6 kW, which is a current of 31.25 amps, so there is more of a demand on the power supply wiring etc. The transmission losses increase by 56% with the extra current. In both cases the customer is charged for power used, 6 kW. That is why the supply companies do not like loads with a poor power factor and sometimes charge commercial customers more for a poor power factor. That in turn makes it viable for the customers to correct the power factor of the load they place on the supply.
Can i reduce electric bill by improving power-factor?
For a residential consumer, power-factor improvement has absolutely no effect on one's electricity bill. Adding power-factor improvement capacitors at the point of supply will have absolutely no effect upon the operation of the load circuits, but it may act to reduce the supply current. But reducing the supply current will not reduce one's energy consumption.

How can you improve your power factor in your Factory?
Improving the power factor of an industrial load acts to reduce the load current delivered by the electricity utility company, enabling them to reduce the amount of copper used in the supply lines, transformers, circuit breakers, etc. It also prevents the electricity utility company imposing a penalty charge applied to the factory's energy bill. The most common method of improving power factor under these circumstances, is by installing a capacitor bank at the supply's point of entry at the factory. It is also possible to install capacitors at individual inductive loads. Power factor improvement does not apply to residential loads, and any company offering 'power-factor improvement' capacitors for residential loads is a scam.

Will the improvement of power factor will increase the efficiency?
Efficiency is defined as the ratio between the output power and the input power of a machine, expressed as a per unit or percentage. Power factor improvement has absolutely no effect on the behaviour of a load. All it does is to reduce the magnitude of the load current. A reduction in load current means that less copper can be used in the supply of energy to the load. However, it doesn't effect either the output or input power of the load. So the answer is no, power factor has no effect on the efficiency of a load. You could argue, however, that if improving the power factor of a load reduces the supply current, leading to lower line losses, then there is an improvement in the efficiency of the supply system.
What agencies determined money supply?
Money supply is determined exogenously by the monetary authority usually central bank of a country.
What components define the system's form factor?
The mother board, power supply, and chassis
What is the determinents of supply?
It is the factor when they change they cause supply curve to shift to either left or right.
