The effect of low (or 'poor') power factor is that a given load requires more load current than at high power factors. So, to accommodate these higher currents, a greater volume of copper is required in the supply cables, switchgear, Transformers, etc. So much greater capital costs are required if low power loads are supplied.

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 economic dispatch control?
It is the operation of generation facilities to produce energy at the lowest cost to reliably supply power to customers, recognizing operational restrictions of generation and transmission facilities.
How do you save energy with power factor correction?
Power-factor correction doesn't save energy. Power-factor correction is used to reduce that magnitude of the current drawn from the supply in order to minimise the cross-sectional area of the supply conductors and associated equipment -thus keeping down the cost of the supply circuits which are owned by the supply company. Power-factor correction doesn't apply to homes, but only to larger commercial or industrial premises. The electricity supply company will negotiate a value of power factor for the load, and apply a penalty charge to the customer if his load is not kept within that agreed value.
What is the effect of leading power factor on transformer?
that is to reduce the cost of the power plant.... Improving power factor(increasing the ration active/apparant power morethan 0.8) will increase the efficiency of uer system. Improving power factor denotes eleminating the recative power(which do no average work).... If u have more capacitive parts in uer system, the power you may need be really high when the capacitor is charging. But as it is in an a.c. system, used energy will be released and hence the average energy consumption of the cap is null. As in one instance iot absorbes energy, the electricity distributers must be able to generate such an high power which will incrrease their cost(eventhough the absorbed energy will be released)!!! Just by reducing the the reactive power, you can reduce the enery absorption. However to do so, you may have to use caps/inductors whcich will cost you a lot. Generally, electricity distributors say, "You must not reduce uer power factor than 0.8"... In some countries, distributors pay for the factries if there power factor is higher than a cirtain value(0.95).... -R-
How do you calculate the cost of electricity bill of a 3 phase 125kW induction motor running at 400v 50Hz motor running for 8 hrs condition if 1000w equal to Rs0.238?
To answer this question, i need the power factor of the motor.CommentYou don't need the power factor, as you already know its true power (watts), but you do need to know the efficiency of the motor to determine its input power. You also need to know the cost per kilowatt hour.But you can get a rough idea by multiplying the number of kilowatts, by the time in hours, by the cost per kilowatt hour. For a more accurate answer, you need to divide this by the efficiency of the motor.
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 Cost of 1 MW generation of power in thermal power plant?
The cost of 1 MW power generation is Rs. 5.0 crores in thermal power plant.
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.
How much energy you can save by improving the power factor from 0.8 to 0.98?
None. Power factor improvement has no effect whatsoever in saving energy. <<>> What it can save you is money. A utility company will charge an additional cost on your regular bill for having a low power factor reading less than .92 depending on the type of service. It is billed as a surcharge to the addition cost of the bill. On three phase services this correction can be done by adding capacitance to bring the power factor up to .92.
