Installation of capacitor bank shall be carried out in accordance to project specifications and approved drawings and technical submittals etc. Installation will be carried out by skilled and suitably experienced electricians under supervision of highly competent site supervisors and engineers to ensure the correctness and quality of the work. Prior to dispatch of capacitor bank equipment,… Read More »
At the stage of receiving the cables at project site, inspect the protective covering on the cable for evidence of shipment damage. Leave the factory-applied protective cover in place until removal is absolutely necessary. Where possible, check the copper sheath for evidence of shipment damage. When cable drums are unloaded in designated area, provide wooden… Read More »
Insulator Definition: Electric insulators are substances through which electric current cannot pass easily like glass, mica, dry air and Bakelite etc. Similarly materials which resist the transfer of heat are called thermal insulators like wood, glass wool, rubber etc. The materials which have very high resistivity i.e. offers a very high resistance to the flow… Read More »
Electrical wiring is process of systematic laying of wires for the smooth flowing of electricity current at different places like houses, buildings and hotels with utmost safety and precautions. Electricity wiring generally refers to insulated conductors used to carry current from main panel to and associated devices and equipment. If we divide the wiring in… Read More »
The AWG – American Wire Gauge – is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. The AWG table below is for a single, solid, round conductor. Because of the… Read More »
Purpose of Isolators is to ensure that an electrical circuit is completely de-energized in order to conduct the service or maintenance. Isolators are also familiar as isolation switches for isolating the electrical circuits, such switches are often found in electrical power distribution and industrial appliances and other applications, where it is critical that machinery must have its source of driving power removed for adjustment or repair. High-voltage isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers, transformers, and transmission lines, for maintenance. The disconnector switch is usually not intended for normal control of the circuit like circuit breakers, the main purpose… Read More »
