This document summarizes an industrial training program at Leela Electric Power Services Pvt. Ltd. from May 1-30, 2015. It discusses the company's services including power distribution consulting, transformer installation, and switchboard erection. It outlines the workflow for electrical design projects, including load analysis, fault calculation, equipment selection, and standards compliance. Specific techniques covered include earthing, cable termination, control panel architecture, interlocking, and power factor correction. A case study of a food processing plant project is presented detailing its load requirements. The conclusion restates that the training familiarized participants with design workflows and techniques.
INDUSTRIAL TRAINING
- 1. INDUSTRIAL TRAINING Leela Electric Power Services Pvt. Ltd., Ernakulam 01-May-2015 to 30-May-2015
- 2. Plot About the company Work Flow A Case Study Gallery Conclusion
- 3. Leela Electric Power Services Pvt. Ltd. Consultancy of Power Distribution Estimation & Design of Electrical Schematic Erection, Testing and Commissioning of Transformers up to 2000KVA and HV/MV switchboards
- 4. Leela Electric Power Services Pvt. Ltd. Erection of Control panel and its wiring Erection of 2-pole,4-pole and 6-pole receiving structure and allied works End termination of HT cables up to 33KVA
- 5. WORK FLOW
- 6. DESIGN Starts from load side Based on Standards by Electrical Inspectorate Fault Level Calculation & Earthing Scheme Per Motor Design Switch Fuse Isolation (MCB, MCCB, SFU and MPCB) Cable
- 7. STANDARDS Chief Electrical Inspectorate, Govt. Of Kerala http://www.cei.kerala.gov.in Norms and conditions Eg. Power Distribution Board 3000 W or 2 Points Low Voltage Distribution Board 800 W or 10 Points
- 8. EARTHING Body Earthing of Equipments Earthing Scheme & Grid Formation Earthing wire Fault level variation according to place of fault Copper Aluminum Galvanized Iron
- 9. EARTHING
- 10. EARTH PLATE Copper and GI plates 60 cm x 60 cm x 3 mm / 6 mm ( Min. Dimension) No. of plates based on fault level
- 11. PLATE EARTHING
- 12. PLATE EARTHING
- 13. 51G Earth Fault Relay Inverse time over current relay Severe fault Fast tripping Main protection relay used below 500kVA
- 14. A2XFY cable A Aluminum 2X XLPE insulation F/ Fa Steel strip armor variations W/Ww/Wa Steel round wire armor variations Y PVC outer sheath C/CE Metallic screening
- 16. Basic Architecture of a Control Panel
- 17. INTERLOCK Why interlocking ? Methods Automatic Mains Failure Relay (AMF) Castell Key Mechanism Crusher Loads The plant never sleeps High speed interlock required Automatic Transfer Switch (ATS) is used
- 18. Automatic Transfer Switch Monitors Voltage and Frequency Fast switching (30 Cycles) Synchronization Two live lines handling simultaneously
- 19. Automatic Power Factor Correction Panel Optimize energy consumption Increase the power availability Reduced KVA requirement Reduce harmonic distortion
- 20. ISOLATION EQUIPMENT ORDER RATING MCB Less than 500 A MCCB 500 to 1 kA ACB, VCB, SF6 above 1 kA
- 21. MCCB and MCB Difference ? 3- Phase 4/6 way TPN MCB DB 4/6 ways in each phase Percentage tripping requirement ?
- 22. TOD Meter Time of Use Meter Peak and Off Peak Slabs Measures When Energy is Consumed How much Energy is Consumed
- 23. CASE STUDY Avees Food Products, Pulincunnoo, Aleppy Washing Powdering Roasting Grading Packing Load Requirement 290.75 HP 14.7 kW 80 kVAr
- 24. Glanding
- 26. CONCLUSION HT wiring Design and Standards is familiarized Workflow and Procedures are familiarized Techniques like cable glanding and termination are familiarized AUTOCADD electrical drawings are familiarized
- 27. THANK YOU ALL VERY MUCH
