ADARSH KUMAR

This document summarizes a site visit report for an electrical engineering summer internship program. It details a visit by interns to a 132/33 KV substation in Allahabad, India. The interns were given an overview of the substation's components and operations by assistant engineers, including learning about protection equipment, transformers, circuit breakers, and the SCADA system. The purpose of the visit was for the electrical engineering students to gain practical knowledge of power transmission and distribution. The interns concluded they benefited from seeing the equipment in person and having the chance to discuss with substation staff.

Conclusion 7 ACKNOWLEDGEMENT We are gladly & thankful to Dr. Navneet Kumar Singh sir and Dr. Niraj Kumar Choudhayr Sir and SIPEE -2018 Team who decided to take visit in 132/33KV Substation, Teliarganj-Allahabad We are especially thankful to respected assistant engineers of Teliarganj- Substation who gave the proper guidance to us and gave practical based approach learning to us.
GENERAL INFORMATION An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps. Teliarganj substation that has a step-down transformer decreases the voltage(133/33KV) while increasing the current for domestic and commercial distribution. PURPOSE OF VISIT Our main purpose for this visit is to be get practical knowledge of electrical power transmission and distribution We are Electrical Engineering student so we will get the idea of electrical power transmission and distribution. we will also get familiar with Transformer maintenance, circuit breaker, Transformer isolator, bus bar, Protective relays, Lightening arresters, Load break switches
WHAT WE LEARN? On 2nd july. ,2018 (Monday) at 03:00 pm we reached at Teliarganj- Sub Station Introduction About Single Line Diagram, Different Protection Equipment, SCADA system At the beginning, one of the assistant engineer explained all the essential component of the 133KV substation and explained one line diagram of Teliarganj
.Sigle line diagram,132KV substation Teliargnaj Key Points:- 1. Different Protection Equipment: break switches, 2. SF6-Circuit Breakers: Due to the unique properties of SF6, it is used for 132KV lines protection. . Some of the outstanding properties of SF6 making it desirable to using power applications are: 1. High dielectric strength 2. Unique arc-quenching ability 3. Excellent thermal stability 4. Good thermal conductivity
3. Lightening arresters: Lightening arresters are provided in order to discharge the high voltages. It acts as main protective device for feeder. 4. Capacitance Voltage Transformer: After the Lightening arresters Capacitance Voltage Transformer CVT which together with the Wave trapper acts as LC circuit follows it. In this substation, we used CVTs in the place of PTs because it easily passes high frequency signals"www.powergridindia.c. om 5.Step down Transformer is used to step-down the voltage level from 133KV to 33KV by using 6. Battery Room: There are three panel of battery source one is for PLCC, it is 48v, two panels are 220v, and it is for relay operation and many more application. These batteries are charged when AC supply is ON.
CONCLUSION From this visit, we got the information and practical knowledge about Power Distribution and Transmission. Student got the knowledge about different protection devices used in substation. They got the idea how to read the one line diagram of power substation using different symbols used in diagram. Student cleared out practical knowledge of transformer as how it step down voltage 133 KV to 33 KV.They also got knowledge about new SCADA based system as you can operate substation by manually or by command from computer using SCADA system and PLC programming. About 46 students were benefited from this visit as they got chance to discussion with assistant engineers working at Substation.
