Introduction of Indoor Switchgear – Advantages and Limitations of Indoor Switchgear

Switchgear is a general term given to a unit that is a combination of safety control and measurement types. Switchgear can be of different forms depending on the type of applications such as feeder protection, motor protection, rail traction purposes, metering etc. For example, switchgear installed in power substations performs various functions such as connection of incoming feeders and busbars along with transformer units, circuit breakers and relaying devices using a combination of short-circuit current interrupters, capacitors, etc. Switching banks, current and voltage measurement, monitoring and control, battery storage etc. Depending on the voltage level as well as economic stability. , switchgear can be of indoor or outdoor type. Indoor switchgear is mostly used for medium voltage also known as MV switchgear and is enclosed in a metal enclosure which is grounded. Voltage levels from 3-36 kV can be called medium voltages. However, in recent times indoor switchgear has also been successfully used for high voltages above 36 kV. In the following sections, we will try to limit our discussion mainly to internal switchgear.

Advantages of Indoor Switchgear:

  • More reliable and secure.
  • Takes up less space than external systems.
  • Easy maintenance and durability.
  • Lower operating costs.
  • Grounded metal enclosures reduce the risk of electric shock.
  • More security.
  • Low risk of environmental conditions.

Limitations of Indoor Switchgear:

The significant drawback of indoor switchgear contrasted with outside is the higher establishment costs. Additionally, for financial reasons and at higher voltages, an outer framework or air protection framework turns out to be all the more monetarily achievable.

In the past areas, indoor switchgear frameworks were talked about and contrasted and open air switchgear. Inside switchgear courses of action are profoundly dependable, safe and savvy. They are profoundly adaptable and solid when contrasted with outside partners. They can endure unforgiving ecological circumstances. Notwithstanding, financial possibility and high voltage levels limit the utilization of indoor switchgear frameworks.
