1) Why ELCB cannot work if Neutral input of ELCB does not connect to ground? ELCB is used to detect earth leakage fault. Once the phase and neutral are connected in an ELCB, the current will flow through phase and that same current will have to return neutral so resultant current is zero. Once there is… Read More »
What is Electronics? Electronics can be defined as the science of how to control electric energy, electrical energy is the form of energy in which the electrons have a fundamental role. The field of basic electronic also deals with electrical circuits which involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated… 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 »
Below is given the method statement for performing the installation of optical fiber cabling system for a project. The method is given from receiving the material on the installation site and what to do after that. Make sure that for all drawings and schedules necessary approvals are available. Offloading and handling of Fiber Optic cable Adequate… Read More »
As you are familiar with the principle of a DC motor or DC machine that when it is loaded either as a motor or as a generator, conductors of the rotor are carrying the current. To better understand the concept, imagine the conductors which are laying in the magnetic field which is present in the… Read More »
Direct current or DC machines are used for the conversion of one form of energy to another. Similarly a DC Generator is used to generate the energy which works on the principle of converting mechanical energy into electrical energy. Basic law or principle behind the generator is the Faraday’s law of electromagnetic induction which states that… Read More »
