In a substation the following equipment is not installed
A. Exciters
B. Series capacitors
C. Shunt reactors
D. Voltaire transformers
Answer: Option A
Solution (By Examveda Team)
Definition: A substation is a part of the power system used to transform voltage levels, control power flow, and provide protection and switching operations.Equipment in substations: Common equipment includes series capacitors for voltage support, shunt reactors for reactive power control, and voltage transformers for measurement and protection purposes.
About exciters: Exciters are devices used to supply DC field current to the rotor winding of synchronous machines such as generators or motors. They are installed in power plants or generator systems, not in substations.
Reason: Since substations do not contain generating units, there is no need for exciters, making them absent from substation installations.
Conclusion: Among the given options, exciters are not installed in substations.

The frequency of voltage generated, in case of generators, can be increased by
A. Using reactors
B. Increasing the load
C. Adjusting the governor
D. Reducing the terminal voltage
In aluminium conductors, steel core is provided to
A. Compensate for skin effect
B. Neutralise proximity effect
C. Reduce line inductance
