Answer 1

Classification of switchgear

Switchgear is broadly classified based on the voltage levels and the environment in which it is installed. The two main types are:

Indoor Switchgear

Used for low and medium voltage applications (typically up to 36 kV).
Installed inside buildings or enclosures to protect from environmental factors like rain, dust, and extreme temperatures.
Example: Metal-clad switchgear used in industrial plants.

Outdoor Switchgear

Used for high voltage applications (above 36 kV).
Designed to withstand environmental conditions like storms, humidity, and temperature variations.
Example: Air-insulated or gas-insulated switchgear in substations.
