IEEE UET KSK arranged a study tour to Nearby Grid Stations, which included 132KV GIS SAGGIYAN GRID AND 132KV AIS SHAHDRA NEW GRID. Its main functions are to receive electrical energy at high voltage provided by the power stations. Then it reduces the provided voltage to a certain value that is efficient for local distribution. First, it Step-Down 220-KV electricity into 132-KV electricity, which is further step-downed to 66-KV then 11-KV. This tour was a great initiative by the society as it was full of information for the students. They came to acknowledge the many types of equipment and components used in real life to transmit electricity to the consumers.
The tour included two types of grid stations for better understanding for the students. One was an Air-insulated substation(AIS), and the other was Gas insulated substation(GIS). The differences between air-insulated substation (AIS) and gas-insulated substation (GIS) are vast. There are five major considerations in the differences between the two high voltage substations: their construction, installation, operation, ongoing maintenance, and total cost of ownership. This system occupies almost 10 times greater space than GIS but can be used for large scale transmission. For safety, purpose pebbles are placed over the base of transmission pylons for maximum grounding.
The tour’s main purpose was to help the students with their 4- year Bachelor program at the University of Engineering & Technology Lahore, Pakistan.
The students focused on learning practical concepts related to the field. They learned to solve daily life Electrical related problems and learn about Electrical distribution systems.
This tour provided the aspiring Engineers with the most valuable opportunities for thorough learning and understanding. Respected faculty members also joined this tour and gave students precious instructions and put the students in contact with experts in the field, who gave extensive guidance regarding many practical issues.
We are thankful and appreciate the guidance of Mr.Waqas Ahmed. He thoroughly explained the substation’s working and its various components, which include Primary power lines, Ground wire, Overhead lines, Transformer for measurement of electric voltage, Disconnect-switch, Circuit breaker, Current transformer, Lightning arrester, Main-transformer, Control building, Security fence, Secondary power lines.
As one can conclude that electricity plays an important role in our life. That’s why various protective measures are taken to protect the substations from various faults and smooth functioning. At the end of this educational trip, The students learned about the various parts of substations and how they are operated.
