High, medium, and low voltages or switchgear are the terminologies that we mostly hear when the discussion is about voltage classifications. These classifications range differently and depend upon where you live. The switchgear is attached to the switches in order to control the electrical equipment. Low voltage switchgear and medium voltage switchgear are way too different from each other, let us have a look at different factors that makes both of these switch gears distinguished.
Supply
Big factories that require higher or medium voltage require the same qualified switch gears too. Their electric utility supply makes sure through a substation and these substations are divided into voltage levels and switch gears are connected accordingly. This substation makes sure to distribute the electricity to all the parts of a factory or any building. However, low voltages require low voltage switchgear and the power can be easily routed through the distribution system and there is no need of setting and building up any substation for the purpose.
Controls
Any system or machine that utilizes low voltage or medium voltage is the basics on which the control system is determined. All buildings specifically factories require adequate powers. The low voltage switchgear has three power distribution products designed in order to make the electric power very sufficient. Low voltages are easy to control and provides a reliable and efficient power supply. Low voltage switch gears guarantee the protection of the elements against thermal stress. It controls the function and gives room for modification of a loaded system by the operating system. While, on the other hand, medium voltage switch gears have distinguished busbar systems which has bolts for torque resistance, which are way different than low voltage switch gears. The feeders are tripped in every four eyes, and then draw out for interlock, and cable tightness is also carried in every four years
Electric energy is a vital part of our lives. These differences between low voltage and high voltage switch-gears do not affect the quality work and assistance of these switch gears. It plays an important role in residential especially industrial areas. The use of switchgear is highly recommended because of its extensive features and functions
The one basic function of low switchgear and medium voltage switchgear is similar as both of these switch gears interrupt the short-circu it and prevent all sort of fault currents, and maintains unaffected circuits at a time. Switchgear provides isolation of circuits from the power supplies.
