Switchgear protects appliances and equipment from damage from overloading and short-circuit. Switchgear also provides a way in which electrical equipment can be de-energized and faults can be cleared.

Here our experts at RR Switches, a leading switchgear company, answer FAQs on switchgear:

• What is an electrical switchgear composed of?

An electrical switchgear has electrical disconnectors, fuses and circuit breakers. All these protective devices interrupt the overloaded circuit while still allowing the current to flow through the unaffected circuits. They protect electrical equipment and appliances from damage by isolating the faulty circuit.

• What are the common accidents associated with switchgears?

Some of the common electrical accidents include:

• Electric shocks and burns: When a person touches an exposed wire or a live electrical part, they can receive a shock. It can be a minor shock or a severe one, depending upon the voltage. A shock wave can even throw a person across the room, causing severe injuries.
• Fire and explosion: Excessive flow of current can lead to explosions that can damage property and hurt those who are in close proximity. A faulty wire can also cause sparks to fly which can burn flammable materials lying nearby.
• Heat build-up: In case of too high voltage, wires and cables can melt. This can be dangerous for workers who may accidentally come in contact with the exposed part of the cables. It is therefore important to choose cables and wires as per their recommended applications.
• Mechanical hazards: As switchgears power electrical motors, an accident can occur when the switchgear malfunctions or is accidentally switched off.
• What are some safety precautions that must be followed while working with a switchgear? Scheduling a periodic inspection is the best way to accurately know the condition of the switchgear. It should include proper examination of the switch room, access control, the environment, the moisture level in the place, corrosion and fluid leaks. and anything relating to the switchgear environment. In addition to the inspection of the switchgear, ensure that the safety procedures are being followed. The switch room should always be dry and cool. Excessive levels of humidity can adversely affect the function of switchgear. All the components should have proper insulation to avoid electric shocks and electrocution. Access to the switch room should only be given to the authorised personnel. Untrained workers should not have the access to switch rooms or should be continuously supervised.
