Electric heaters are truly a benefiting electrical device that has the function of converting a current of electricity into heat energy. Usually, the electric heaters can ideally be used anywhere inside homes and offices. A vast number of people use electric heaters as it requires just turning on the socket switch and the heater will start to produce heat. Modern…
Generally, a power surge can follow in any wire in your very new or old home and threaten any device plugged-in inside your house. Despite all many householders have a false assumption that surge protection is just a matter of plugging their devices into one among those low-cost, multi-outlet surge suppressors. What is a Power Surge? A power surge may…
Current Transformers (CT) are the devices in which the secondary current used for calculation is proportional to the primary current produced by the electrical network. For this purpose, the primary current is tapped from the transmission line and stepped down in the secondary for measurement purposes. In series with the current lead, the connection to the primary winding circuit is…
Recently we installed and commissioned 2nos MWM TCG 2020 V 16K Gas Generator in our factory. Right now those two Gas Generators are the main power source for all types of machinery inside the factory floor. Those two Generators can generate a maximum of 3000KW at 100% load. But for a better life, it’s best practice to keep the load…
If you own a manufacturing plant, a factory assembly line, or any other automated space that can benefit from having its certain components operate at different speeds and frequencies, variable frequency drives (VFDs), also known as AC drives, can be of immense help. That said, while VFDs have grown more popular over the past few decades as our factories and…

Bangalore is one of the modern and well-developed cities in India. It is called the Garden City for a reason. From its weather to its urban culture, the city has good vibes that attract the attention of people from other states to come, work and live in it. A stable supply of electricity has been one of the drivers of…
Maintenance of GIS: Experience has shown that the internal parts of Gas Insulated Substation are so well protected inside the metal enclosure that they do not age and as a result of proper material selection and lubricants, there is negligible wear of the switch contacts. Only the circuit breaker arcing contacts and the Teflon nozzle of the interrupter experience wear…
Installation: The GIS is usually installed on a monolithic concrete pad or the floor of a building. It is most often rigidly attached by bolting and/or welding the GIS support frames to embedded steel plates or beams. Chemical drill anchors can also be used. Expansion drill anchors are not recommended because dynamic loads may loosen expansion anchors when the circuit…
Electrical and Physical Arrangement: For any electrical one-line diagram there are usually several possible physical arrangements. The shape of the site for the GIS and the nature of connecting lines and/or cables should be considered. Figure 1 compares a “natural” physical arrangement for a breaker and a half GIS with a “linear” arrangement. Most GIS designs were developed initially for…
