If the specific resistance of the conductor is increased, what effect does it result on the skin effect?

• remains the same

• decreasing

• increasing

• none of the above

The capacitor bank is installed

• to improve the power factor and voltage magnitude

• to decrease the power factor and voltage magnitude

• to improve the power factor only

• to improve the voltage magnitude only

The disadvantages of transmission line as compared to cable system are

• atmospheric hazards

• atmospheric hazards, exposures to lightening

• interference of telecommunication circuits

• atmospheric hazards like smoke, ice fumes, exposures to lightening, interference of telecommunication circuits etc.

Pole mounting substations are also known as

• outdoor type

• indoor type

• basement type

• open type

In practice, the cost of energy transmission in minimum for

• natural gas power plants

• diesel power plants

• nuclear power plants

• steam power plants

The peak load demand of an industrial area is met by

• nuclear power plant

• storage batteries

• diesel power plant

• steam power plant

The main objective of tariff is to distribute equitably the cost of

• a. installation and fuel

• b. power transmission and distribution

• c. both (a) and (b)

• d. supplying energy among various classifications of use

Factors involved in fixing tariff are

• secured return from each consumer

• simplicity, cheapness and easy explainability

• incentives to consumers and charge according to use

• all of these

Disadvantages of low power factor are

• high rating of generating, transmitting and distributing equipments

• large voltage drop and poor voltage regulation

• large copper loss and high capital cost

• all of these

A circuit breaker serves the purpose of

• switching-on and switching-off under normal working conditions

• protecting the circuit under abnormal condition of load

• protecting the circuit under faulty conditions

• all of the above
