Switchgear Power Systems for Industrial Use
Switchgear is the name for electronic devices that control the usage of electricity in a power system. These devices are important because they can potentially stop an overload from occurring. They can also remove the energy from circuits, allowing them to be tested or repaired. Switchgears can ensure the dependability of a power supply so that outages are less likely and is directly responsible for the reliability of the electrical supply.
How are switchgear power systems Utilized?
switchgear power systems are generally placed on both sides of an electrical transformer. One side is high and the other side is low voltage. Low voltage switchgear can be placed in a building, provided the proper circuit breakers and safety equipment are installed. high voltage switchgear can withstand voltages of around 1,100kV. In an industrial setting, the switchgear and transformer may be placed together in protective case, which is known as a unitized substation.
There are many different classifications for switchgear, such as by voltage class or insulating medium. It is also common to classify them by construction type and interrupting device. Industrial and utility are common construction types. Fuses and various types of Circuit Breakers are considered interrupting devices. They may be classified by application, such as distribution or transmission. Of course, the type of current the device uses, either alternating current or direct current, is one more way of differentiating switchgear.
Critical Shutdowns in an Emergency
The word control is used in switchgear power systems to refer to measuring the amount of power in the system. The ability to switch or stop power in an emergency is critical. By controlling it, the safety of humans and animals, as well as property is protected. Switchgear enables this to be possible. This is especially important in an industrial environment, where a power surge could cause severe damage, as well as injuries. Functioning and well-maintained switchgear power systems can continue to operate for years, but just as important as maintenance is continual checking. Indoor, as well as outdoor switchgear equipment should be tested, often by the use of thermal imaging. With this technique, catastrophic failures can be prevented before they occur. Other methods of testing are also available. A partial discharge test or the use of ultrasonic detectors can determine the viability of outdoor switchgear systems.
A main purpose of switchgear is to prevent any problems such as overloads and continuing to supply power to all of the properly functioning circuits. Switchgear also has the ability to keep circuits separate from their respective power sources. Proper maintenance is critical to the correct functioning and safety of your switchgear devices. Many fatal explosions and fires have been directly linked to faulty or poorly maintained switchgear. It is advisable to follow the preventative maintenance programs designed by the National Fire Protection Organization (NFPA) and the International Electrical Testing Association (NETA).
