In a power system consisting of generators, transformers, transmission and distribution circuits, it is inevitable that sooner or later some failure will occur somewhere in the system. When a fault occurs on any part of the system, it must be quickly detected and disconnected from the system. The detection of a fault and disconnection of a faulty section or apparatus can be achieved by using protective relays in conjunction with circuit breakers. Protective relays have technologically advanced from electromechanical relays to numerical protection relays. This numerical Relays provide you with unique microprocessor-based devices that eliminate unnecessary trips, isolate faults, protect Generators, transformers, feeders and motors, and provide system information to help you better manage your system.

This intensive 2-day workshop aims to expound electrical protection relay principles and application by thoroughly explaining with detailed discussion and real-life examples of generator, transformer, feeder and bus-bar protection schemes. Moreover, correct overcurrent relay application requires knowledge of the fault current that can flow in each part of the network, hence fault level calculation, unrestricted forms of line protection, such as overcurrent and distance systems will be addressed. The course will equip engineers, technicians, planners etc. with essential knowledge and state-of-the-art protection schemes.

Electric motors accounts for over 76 % of the power used by industry and they have always had an impact on operating costs. Conservation of electricity in electric motors and the systems they drive has been a subject of increasing concern recently. Everyone is trying to find more efficient and cost-effective ways to operate their facility. Choosing appropriate energy efficient motor, performing accurate power factor correction and application of variable frequency drives in our industrial environment are ways to operate more efficiently and cost-effectively. This course seeks to address the most common causes of poor power factor, modern power factor correction technologies available for various industries and how to design, improve and maintain an impressive power factor thus minimising related operational inefficiencies. Moreover, the course will cover the basic operation of a VFD, various applications in which a VFD can be installed, calculation of cost savings as well as some rebate information you will need to know. We will explain what information is needed in order to help Industrial Controls choose the correct VFD for your application. This course will certainly assist participants enrich their establishments with significant benefits:

• Reduce energy costs,
• Improve motor-driven system reliability and efficiency,
• Increase productivity, and
• Minimize unscheduled downtime

• Get to know if what you are doing is currently compliant with the new edition of the standard.
• Get acquainted with medium voltage installation components.
• Obtain in-depth knowledge of the standard requirements for the installation of MV components.
• Imbibe concise knowledge of medium voltage earthing principles and concepts.
• Get familiar with basic medium voltage electrical protection and protection schemes.
• Grasp inspection, testing and commissioning procedures of MV installations.

Delegates who take this 2-day course will:

• Have overall understanding of substation technology.
• Understand the concept of substation design practices and equipment selection.
• Acquire in-depth knowledge of substation earthing design, determination of step potential, touch potential, grid potential rise etc.

One of the main objectives of earthing electrical systems is to establish a common reference potential for the power supply system, building structure, plant steelwork, electrical conduits, cable ladders & trays and the instrumentation system.

The importance of human life and the advances in electrical and electronic technology, and its increased sensitivity and scope for increased consequential losses, together with the introduction of SAN 10199, SANS 62305, SANS1063, SANS 10200, SANS 10292, SANS61024 etc., has further lifted the requirements for a professional approach to the provision of Earthing and lightning protection. Moreover, in electrical systems, fault currents can be caused by lightning or electrical faults and a low impedance earth must be present for the safe dissipation of the fault current. The purpose of a lightning protection system and effective earthing, therefore, is to control the passage of a discharge in such a manner that prevents personal injury or property damage. Installations where lightning protection is highly desirable are: high rise buildings, power stations, substations, factories, mining areas, television stations, radio stations, telecommunications stations etc.

It is important therefore that an effective earthing system (lightning protection earthing and electrical earthing systems) be properly designed and installed specifically to the unique requirement of the structures to be protected.

This 2-day course which is based on appropriate SANS, IEEE & IEC standards has been prepared to enhance understanding of earthing, bonding and lightning protection of electrical equipment and building structures. It is aimed at equipping learners with in- depth knowledge of purposes and various methods electrical system earthing, bonding and lightning protection system design, implementation, maintenance and testing.

SANS 10142 is a national adoptable standard for the safe installation of electrical wiring in South Africa. In some cases, the content of SANS is amended, altered and may even be rejected in order to address identified flaws or to cope with the technological advancement. Since 1978 to date, SANS 10142-1 for low voltage installation has undergone series of amendments and in March 2012, edition is 1.8was published. However, with the advent of electric vehicle charging station, UPS equipment and PV installations off-grid or on-grid, secondary supply network or distribution system, electrical installations in hazardous locations, a new edition 2 was approved for publication in March 2017. Therefore, it is the responsibility of every user of electricity to comply with this new edition.

In this 2-day intensive and interactive course, participants will be provided with in-depth review of this new edition of SAN10142-1-2017. The course will in detail, elaborate on the need to ensure that people, animals and property are protected from hazards that can arise from the operation of an electrical installation under both normal and fault conditions. Therefore, installation requirements regarding conductors, cables, distribution boards, circuit breakers, fuses, switchgears, transformers, Motors, PV installations, earthing, bonding, protection etc. will be presented. Testing, measurement, verification and certification of low voltage installations will be elucidated.

Delegates who take this 2-day course will:

• Get familiar with all aspects of maintenance and testing and make use of state-of-the-art tools and techniques for evaluating transformer conditions.
• Obtain timely, practical advice on how transformers work, how they are protected, how they are best maintained, and how to test and evaluate their condition.
• Get familiar with the different protection relays and the basic principles of the different protection schemes including electromechanical and numeric protection relays.
