Essential features of switchgear are: Correct Answer All of these

The essential features of switchgear are:

Complete reliability:

  • Switchgear is added to the power system to improve reliability
  • When a fault occurs on any part of the power system, it must operate to isolate the faulty section from the remaining circuit

 

Certain discrimination:

  • When a fault occurs on any section of the power system, the switchgear must be able to discriminate between the faulty section and the healthy section
  • It should isolate the faulty section from the system without affecting the healthy section
  • This will ensure continuity of supply

 

Quick operation:

  • When a fault occurs on any part of the power system, the switchgear must operate quickly so that no damage is done to generators, transformers and other equipment by the short-circuit currents
  • If the fault is not cleared quickly, it is likely to spread into healthy parts, thus endangering the complete shutdown of the system

 

Provision for manual control:

  • Switchgear must have provision for manual control
  • In case the electrical (or electronics) control fails, the necessary operation can be carried out through manual control
