The role of Low Voltage Switchgear

National and international standards define the manner in which electric circuits of low voltage installations must be realized. Standards determine the capabilities and limitations of the various switching devices which are collectively referred to as switchgear. The main functions of switchgear are:

Electrical protection
Electrical isolation of sections of an installation
Local or remote switching

Electrical protection at low voltage is normally incorporated in circuit breakers, such as thermal magnetic devices and/or residual current operated tripping devices. In addition, circuit breakers provide:

Over-voltage protection
Under-voltage protection

The aim of protection is to avoid or to limit the destructive or dangerous consequences of excessive (short-circuit) currents, or those due to overloading and insulation failure. The circuit breaker will separate the defective circuit from the rest of the installation.

The operation of switchgear is an important part of power-system control. Functional control Switchgear-control functions allow system operating personnel to modify a loaded system at any moment, according to requirements, and include:

Functional control (routine switching, etc.)
Emergency switching
Maintenance operations on the power system

The operation and maintenance of your electrical switchgear equipment can be complicated and dangerous for the inexperienced. Rely on Carolina Precision Switchgear’s reputation and over 100 years of experience to handle your company’s service requirements.
