Welcome to Electrical Mastar open and free electrical engineering study site.The  Electrical Mastar website is here to offer tips and also help you to  learn more about basic things in electrical engineering. These website is fully covered by almost all electrical oriented topics.

Transmission line maintenance

Transmission lines carry electrical power and their characteristics make them conditional to ongoing checks and inspections. Power transmission lines are made up of towers and they run hundreds of kilometers through vastly different geographies and climates. This characteristic exposes transmission lines to numerous external factors, such as corrosive agents, ice, wind and ultraviolet radiation, which…

IS Standards for Electrical Equipments

Standard Makes for Electrical Equipments: First we have to study about IS  standards for electrical equipments. so we can see all electrical equipments standards one by one.   Sr. No. Item IS No. Makes 1 Transformer IS: 2026/1977 Crompton Greaves, NGEF, Kirloskar, BHEL, Andrewyule, Bharat Bijlee, Alsthom, ABB, Voltamp, Siemens, GEC, Voltas, TELK 2 11 kV/HT…

High voltage DC Transmission system (HVDC)

HVDC stands for High Voltage Direct Current. An HVDC electric power transmission system uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current systems.  For long-distance distribution, HVDC systems are less expensive and suffer lower electrical losses. For shorter distances, the higher cost of DC conversion equipment compared to…

UG cable types

Underground cables are used for power applications where it is impractical, difficult, or dangerous to use the overhead lines. They are widely used in densely populated urban areas, in factories, and even to supply power from the overhead posts to the consumer premises.The classification of Underground cables can be done on the basis of several…
