Circuit Breaker: GIS uses essentially the same dead tank SF6 puffer circuit breakers used in AIS. Instead of SF6 -to-air as connections into the substation as a whole, the nozzles on the circuit breaker enclosure are directly connected to the adjacent GIS module. Current Transformers: CTs are inductive ring types installed either inside the GIS enclosure or outside the GIS enclosure. The GIS conductor is the single turn primary for the CT. CTs inside the enclosure must be shielded from Read More …
Construction and Service Life of GIS Substation
GIS is assembled of standard equipment modules (circuit breaker, current transformers, voltage transformers, disconnect and ground switches, interconnecting bus, surge arresters, and connections to the rest of the electric power system) to match the electrical one-line diagram of the substation. A cross-section view of a 242-kV GIS shows the construction and typical dimensions. Construction of GIS Substation: The modules are joined using bolted flanges with an “O” ring seal system for the enclosure and a sliding plug-in contact for the Read More …
Ten Crazy Trends In The Smart Home Industry
Smart home technology is sweeping across the nation as rapidly as a field fire. Not only that, it is changing the world at the same time. Here are 10 trends in the smart home industry making a huge impact on people’s lives!. 1. Demand For Voice Control 72% of smart home device owners want voice control capability. It’s one of the easiest ways to automate a home. But voice control capability comes at a high price. Interestingly enough this demand Read More …
GIS – Gas Insulated Substations
A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-to-phase and phase-to ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what SF6 can do in centimeters. GIS can therefore be smaller than AIS by up to a factor of 10. A GIS Read More …
Busbar VS Cables for Riser Applications
We already know the using busbar in the power distribution system has many advantages. It is well arranged, safe and reliable. I already posted an article about the Why Busbar Trunking System is Preferred Over Cabling? In this post, we will discuss the Busbar VS Cables for Riser Applications. We will discuss some issue and it will explain the position of using busbar and cable for riser application Main Switchboard Busbar: Need only 1 outgoing for each riser. Lower cost and Read More …
Why Busbar Trunking System is Preferred Over Cabling
Benefits and comparison of Busbar Trunking System are numerous. The total cost of ownership (TCO) is very low compared to conventional cabling system for distribution up to load due to a shorter and easier installation. It required less time & space with low costs. Its overall maintenance is very less. Busbar Benefits and Comparison: Compactness: The Sandwich Construction renders the BBT system more compact than air insulated bus bar system. For this reason, BBT is a preferred choice in the Read More …

For getting uninterrupted electricity, your generators should properly maintain and carefully inspected before the winter. In this article I am going to discuss all about the Winter Preparation for Your Standby Generator. Generator Spend Hard Time in Cold Weather: Sometime it’s really hard to start an Read More …
Light-Bulb Wars: LED vs CFL
In 2018 we already know that LED can save energy when you are using Fluorescent Bulb. And we know that CFLs and LEDs offer a more efficient, longer lasting lighting option. But when come to choice between the two, LED vs CFL, then which one comes out on top? In this article we will share some pros and cons for both Fluorescent light and LED to you for choosing the best one. But at first I want to answer this Read More …
How Natural Gas Generator Can Save Your Life and Money?
Natural gas generator is an ideal choice for areas that are prone to hurricanes. In the hurricane season, the weather conditions are just right for the birth of hurricanes due to warm waters, low-pressure systems, and other circumstances. During late summers and start of fall, hurricanes start forming from Africa and appear as stifling disturbances over the Atlantic Ocean. The low-pressure turbulence is increased with moisture and warmth thus increasing risk for thunderstorms. Thunderstorms may die down over the waters Read More …
