Switchgear is a modern device used to switch the control in electrical circuits and equipment and protect them. . It helps to ensure the maximum continuity of the power supply and acts as a shield for interconnecting devices by controlling, metering, and regulating electricity flow.
Fluctuating power supply is the leading cause of malfunctioning machinery such as motor starters, servo motor etc. Fluctuations can cause damage to the effectiveness of electrical devices and appliances. Switchgear is a modern device used to switch the control in electrical circuits and equipment and protect them. . It helps to ensure the maximum continuity of the power supply and acts as a shield for interconnecting devices by controlling, metering, and regulating electricity flow.
Some essential features of switchgear are:
Complete reliability
Electrical switchgear is vital because it protects the devices from faults and helps regulate the maximum power supply to the devices so that work can be done effectively. If a fault occurs on any part of the power system, switchgear isolates the faulty system and provides continuous power for smooth operation.
Absolutely certain discrimination
Whenever a fault occurs, switchgear isolates the faulty device and provides a continuous power supply to the healthy system.
Quick operation
If any fault exists, switchgear must operate quickly so that no damage is done to the transformers or the generators or other equipment. This helps to protect the healthy parts from being damaged or destroyed.
Provide manual control
Switchgears can be controlled manually if there is electric control failure to protect the device.
There are two types of switchgears:
- High voltage switchgears
- Low voltage switchgears
The three essential functions of switchgear are:
- They provide protection to the devices from interruptions from short circuits or overload fault currents.
- They provide electrical isolation of circuits from the power supply to save healthy devices from faulty ones.
- They enhance system availability by allowing more than one source to feed a load.
The most basic function of the switchgear is to ensure safe operation, along with safety to the personnel working in that setup. There could be many faults and fluctuations in the power supply, so it is essential to protect the power supply chain against every disturbance to ensure smooth operations. . A protection system should be simple to operate, and maintain. There are various types of switchgear and protection devices in power systems like switches, fuses, circuit breakers or relays.
The switchgear and protection devices offered by Schneider Electric India are according to the latest technology and safety standards. Schneider Electric India offers high-quality switchgear that contributes to the stability of operation, maintenance and machine control etc.
