Course description

Course Overview: This Training course will discuss Application, Installation, Operation, Maintenance and Testing issues related to Low‐, Medium‐ and High‐Voltage Switchgear and Electrical Circuit Breakers. The course will provide the delegates with a solid understanding of switchgear theory and standards. The course will also make delegates aware of issues concerning the proper application, installation and maintenance of these types of equipment with a strong emphasis on safety. The course will cover a wide range of material starting from the basics and moving on to more complex issues. The International Electro Technical Commission (IEC) Standard IEC; 62271 will be also exploited during this high technical course, in addition to focusing on Part 110 concerning the High-voltage switchgear and controlgear; Inductive load switching. The IEC 62271-110:2017 is applicable to AC switching devices designed for indoor or outdoor installation, for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1000 V and applied for inductive current switching. It is applicable to switching devices (including circuit-breakers in accordance with IEC 62271-100) that are used to switch high voltage motor currents and shunt reactor currents and also to high-voltage contactors used to switch high-voltage motor currents as covered by IEC 62271-106. This fourth edition cancels and replaces the third edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - all switching devices are now covered, not only circuit-breakers; - a limited number of T10 tests no longer covers shunt-reactor switching tests below 52 kV; - evaluation and reporting of a re-ignition-free arcing time window has been added. The contents of the corrigendum of December 2017 and of February 2018 have been included in this copy. The course also provides an overview of Power System Design and Theory, focusing on the Power Distribution Electrical Circuit Breakers used in common Utility, Industrial, Commercial and Institutional applications. Basic electrical circuit breaker construction, electrical safety, and common circuit breaker maintenance techniques are the major components of this course. There is considerable interest among people who operate and maintain Electrical Power Systems in a wide range of topics relating to equipment maintenance and testing. This is because condition and reliability are directly related to maintenance and testing. To obtain maximum life from electrical equipment, maintain its reliability, and minimize repair cost, it is necessary to serve and test it periodically to predict condition. Proper installation and preventive maintenance of substation equipments will assure continued electrical power supply, it is very important to the consumers specially, for industrial sector where the curtail of electrical power supply is costly. Application considerations with respect to standards, practical recommendations for extension of service life for older, existing installations as well as protective relaying, control and metering are special features of this course.

Target audience

Electrical, Automation, Instrumentation, Communication, Operation Engineers, and Supervisors. The well experienced technicians are also very welcomed.
