Function of Switchgear Power Systems

There are many power supplies available and it is important, especially when working with them, to know the function of each piece of equipment. Switchgear power systems are often enclosed in houses and buildings if there are low voltage levels. For an area with high voltage levels the switchgear power system may be located outdoors. There are three basic functions of switchgear power systems: electrical protection, electrical isolation, and control. Switchgear power systems are the combination of electrical disconnects that serve the function of isolating electrical equipment. The electrical disconnects can either be fuses or circuit breakers. This article will help to explain the main functions of switchgear power systems and there will be some overlap especially in the protective features of this type of power equipment.

switchgear power systems for Electrical Protection

Protection is provided to people and animals, the other power equipment nearby, and the appliances that are connected to the power systems. switchgear power systems allow more than one electrical current source to flow through a load.

The way in which switchgear power systems can detect overcurrents and overloads is through thermal imaging. Thermal imaging is a great technology that helps to detect problems before they cause dangerous situations to occur. Radiation is emitted more with rising temperatures so thermal imaging can catch it before it is too late.

switchgear power systems for Electrical Isolation

switchgear power systems give electrical isolation to the circuits and the part of the system that is energized. These two components can be separated from each other by just a gap or by an actual barrier. This allows protection to the personnel who is performing maintenance or repairs to the power equipment.

switchgear power systems for Control

The control of switchgear power systems refers to control in measuring the electrical load in the system. Emergency switching, emergency stopping, and functional switching are part of the control functions for switchgear power systems. It helps to energize and de-energize an element of a system or just one piece of equipment. The emergency switching, for example, de-energizes the circuit if there is a possible danger to it. The circuit can possibly overheat, cause electrical shock or start a fire. When work needs to be completed, switchgear power systems de-energize the equipment for safety and protection. switchgear power systems offer protection by interrupting circuits that are experiencing an overload while still allowing currents to flow through the circuits that have not been affected by the overcurrent.

switchgear power systems provide protection, isolation, and control. Understanding the function of switchgear power systems can help with understanding how other power equipment works.
