Q. What consideration should be taken during applying a tariff system ?
A. => proper return
=> fairness
=> simplicity
=> reasonable
profit
=> attractive
Q. Classify the tariff system .
A. => simple tariff
=> flat rate tariff
=> block rate tariff
=> two part tariff
=> maximum demand tariff
=> power factor tariff
=> three part tariff
Q. Classify the power factor tariff .
A. => KVA maximum demand tariff
=> sliding scale tariff
=> KW and KVAR tariff
Q. Which tariff is also known as uniform rate tariff ?
A. Simple rate tariff.
Q. Which tariff system is based on classes of consumers ?
A. Flat rate tariff.
Q. In which tariff system charged per unit is constant ?
A. Simple or uniform rate tariff.
Q. On which running charges depends ?
A. It depends on kwh i.e. Number of units consumed by the consumers.
Q. Which is most suitable tariff system for any type of consumers ?
A. Three part tariff.
Q. Which tariff system is normally employed for residential and small
commercial consumers ?
A. Block rate tariff.
Q. Where two part tariff is used ?
A. For industrial consumers.
Q. Which tariffs can be used for big industrial consumers ?
A. => maximum demand tariff
=> power factor tariff
=> three part tariff
Q. What is the relation between power factor and apparent power ?
A. Apparent power is inversely proportional to power factor i.e. KVA ∞
1/cosø .
Q. Why price per unit for first and second blocks of energy is high ?
A. Because the fixed cost , charged on each consumer is merged into the
running charges for these two blocks .
Q. On which fixed charges depends ?
A. Maximum demand of the consumers .
Q. Why consumers having low power factor have to pay more charges ?
A. Low factor of the load means that the load draws more reactive power
from the supply line, so the respective consumers have to pay more charges .
Q. For low power factor a consumer have to pay _______charges.
A. More
Q. Uniform tariff system is ________tariff system .
A. Simplest .
Q. The flat rate per kwh for ________is less than________load .
A. Power , lighting load
