Overview

Dear All,Welcome to the course about "Low Impedance Busbar Protection Panel Schematics". This training is start from very basic level to advanced level. Focus has been given to delivering the practical and hands-on knowledge.Trainer Introduction:Your trainer brings over 21 years of experience in operation & maintenance, erection, testing, project management, consultancy, supervision, substation automation, SCADA, and commissioning. With a background spanning power plants, high voltage substations, and HVDC installations, he has worked with renowned organizations such as Siemens Saudi Arabia. He has been involved in over 20 high-voltage substation projects across Pakistan and Saudi Arabia.His expertise encompasses a wide range of areas including protection systems, substation automation systems, design, testing, and commissioning of power generation systems, high voltage switchgear, protection relays, and control schemes. He has a proven track record of leading testing and commissioning teams for implementing electrical infrastructure projects for industrial clients, including steel and petrochemical industries.Following topics are covered in this training:Introduction to busbar protectionBreaker Failure protection philosophySubstation Single line diagram, shown for busbar protection logicHigh impedance Vs Low impedance busbar protection, advantages and disadvantages of each protectionBreaker Failure stage 1 & 2 operationDirect Transfer Trip in case of Breaker Failure protection stage 2Busbar panel general characteristics Design aspects of the panelExplained the symbols used in the drawingsHow busbar zone is formedLine and busbar isolatorBusbar rating What is isolator replica and why it is requiredCriteria for CT ratio selectionOption of CT ratio selection for low impedance busbar protection Tripping matrix from busbar protection & breaker failure protectionTrip command from busbar protection based on the isolator replicaBasics of schematics, how page is divided in rows and column, how to read cross reference, move between pages.How loop is defined in schematics & how loops are namedAC Supply circuit AC supply change over schemeBusbar protection blocking function, why it is requiredCurrent transformer circuit of busbar protectionPower Supply circuit of busbar protectionTrip and Lockout schematics, CB Close Block, AR Block SchematicsIsolator Replica, CB faulty, DTT, Binary input ConfigurationsDirect Transfer Trip from BusbarDC supply supervisionZ sheet, component drawings, side and front viewThanks
