The Functionality of Switchgear Power Systems

EC Power Systems Explains switchgear power systems

There are several different functions and uses related to the use of switchgear power systems. These functions can include power distribution, safety, testing, and current protection.

Power Distribution of switchgear power systems

Switchgear power systems are used, coupled with an electrical power system (often referred to as a “grid”), that involves the combination of electrical disconnects, fuses and circuit breakers that are used to isolate electrical equipment. switchgear power systems can be used to de-energize equipment to allow for maintenance of the system, as well as clearing any downstream electrical faults. This type of equipment is important, as it is related to the overall reliability and safety of the system’s electrical supply.

Safety and Protection of switchgear power systems

Switchgear power systems can be classified by a number of different ways; these classifications include, voltage class, construction, interrupting device, application and current rating, to name a few. The specific classification of different switchgear power systems will help dictate what is needed for protection and safety of the overall system.

For small or lower-level electrical voltages, switchgear power systems can be housed within a building without issue. Larger-level voltage systems, however, will be outdoors and insulated by the air around it. When switchgear power systems are insulated by air, they require a large amount of space for safe use. Some switchgear power systems are insulated by oil, however, this can pose a spill hazard, therefore, this is not a preferred insulation method.

At its most basic function, switchgear power systems provide protection through the interruption of short-circuit and overload fault currents, while simultaneously maintaining service to unaffected circuits. switchgear power systems also provide isolation of circuits from power supplies. switchgear power systems are also used to augment system availability by allowing more than one source to feed a load.

As switchgear power systems are an incredibly important part of an electrical system, it is critical that they are tested regularly and optimally maintained in order to avoid any potential system failure. switchgear power systems are often inspected using thermal imaging in order to assess the overall health of the system as well as try to predict any potential equipment or system failures that could occur in an effort to avoid a catastrophic situation in the future. Indoor switchgear power systems can be type tested for internal arc containment. This type of test is a critical part of user safety, as today’s switchgear power systems are capable of handling and switching large electrical currents.

The Role of switchgear power systems

Ultimately, switchgear power systems play an important role in the function and safety of electrical systems and grids across the country. Therefore, it is important that these systems are regularly tested and well maintained for optimal functionality in order to ensure safe electrical power distribution to the system’s customers.
