Switchgears – used both to de-energize equipment to allow work to be done and to clear faults downstream – are the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment, in an electric power system, which are important equipment because these are directly connected to the reliability […]


An electric power system is a network of electrical components used to supply, transmit and use electric energy. An example of an electric power system is the network that supplies to a region’s homes and industry with power. Most of these power systems depend upon three-phase power – the benchmark for large-scale power transmission and […]


Any electrical system is regularly prone to faults. When a fault occurs, the normal functioning of the electrical system gets disturbed. The high current resulting from the fault may stress the electrical conductors and the connected equipment thermally as well as electro-dynamically. Arcs at the fault point can cause dangerous or even fatal burn injuries […]


Worldwide, the lighting industry has gone through unprecedented changes. Industrial buildings, like all other workplaces, need well-planned lighting systems to support different activities. While appropriate quantities of light are essential, quality issues are just as important in providing a comfortable and safe working environment. When the lighting facilities in an industrial unit meets both quantity […]


Since lightning has the power to tear through structures, blow up walls made of brick and concrete, mess up steel and stir up deadly fires, the cost of this destruction can be devastating, not to say deadly. The potential losses due to damages to equipment, interruptions to business and injuries to personnel caused by lightning […]


The earthing system is an essential part of the power networks at high-, medium- and low-voltage levels. It is the total set of measures used to connect an electrically conductive part to earth. Elensol emphasises on a systematic approach to the design of the earthing systems, concentrating on the building installation aspects. There are internationally […]
