Short Courses in Electrical Power - 1st to 3rd Dec 2005

Three Days - Short Courses In Electrical Power.

Reported By: Noor Iziddin Abdullah Ghazali.

On 1st December 2005 until 3rd December 2005, the Graduate & Student Section (G&S) organized a Three One Day – Short Course Course at IEM Conference Hall in Design of Low Voltage Electrical System(1st Dec), Planning & Operation of High Tension Distribution Network(2nd Dec) and lastly Simulation Assessment of LV Electrical Installation(3rd Dec). The course were conducted by Associate Prof. Teo Cheng Yu from NTU Singapore.

Associate Prof. Teo Cheng Yu presents the course in-terms of principles and design for low-voltage systems at both the device and system levels. It provides the characteristics,specifications, and industrial standards for circuit breakers, cabling, earthing and fuses. Utility supply systems, utility earthing systems and consumer earthing systems are introduced. Standard design procedures, the latest code of practice, IEE wiring regulations, over current and earth fault protection are illustrated through a series of comprehensive and interesting examples which are particularly useful for the practicing engineers and students. Applications of computer-aided design and simulation are also presented. Common technical terms, design formula, touch-voltage, per-unit calculation and model examination questions with solutions are provided.

For the 1st December, Associate Prof. Teo Cheng Yu give course on Design of Low Voltage Electrical System. This short course is introduce participants to the principles and design considerations in carrying out the design of LV distribution network. Through lecture and the demonstration of dedicated PC-based programs, the participants have a better understanding of the rational of various design criteria and procedures. Thus, they learn how to obtain a comprehensive and sound design, which meets the specified criteria and also the code of practice IEE Wiring Regulations. The main contents are Design Current and Design Procedure, Selection of Protective Device and Phase Conductor and lastly Design of a Benchmark Network.

Second day on 2nd December, Associate Prof. Teo Cheng Yu continue to teach another new topic in Planning & Operation of High Tension Distribution Network. This short course is introduce participants to the high tension (HT) distribution system, planning criteria and scheme of connection. Through lecture and the support of several dedicated PC-based integrated packages, the participants familiar with the criteria and procedure for the planning and operation of the distribution system. The main contents are Planning of HT Distribution System, Analysis of HT network and Protection Co-ordination.

On the last day which is 3rd December, Associate Prof. Teo Cheng Yu teach on Simulation Assessment of LV Electrical Installation. Every installation, either as a whole building or parts of it, shall comply with the safety regulations such as IEE Wiring Regulations. This short course introduce participants to the seven types of critical tests and three types of non-critical tests. Through computer simulation on normal loading, overloading, short circuit and earth fault conditions, each circuit in each DB is assessed accordingly. Design failure if any will be highlighted. These simulation tests provide a mean to assess whether the electrical installation meets the specified criteria and to ensure that safety requirements and IEE Wiring Regulations are met. The main contents are Normal &
Overloading Assessment, Short Circuit and Earth fault Assessment and Motor Starting and non-critical test.

Between the course, there is a good interaction between the speaker and participant in-terms of question and answer. Based on the feedback from the participant, found that they like the content/detailed explanation, speaker knowledge/experienced, informative course materials and lastly the simulation program. Around 108 participant attend this 3 days courses.

In conclusion, this course provides the characteristics, specifications, and industrial standards for circuit breakers, cabling, earthing and fuses. Utility supply systems, utility earthing systems and consumer earthing systems are introduced. Standard design procedures, the latest code of practice, IEE wiring regulations, over current and earth fault protection are illustrated through a series of comprehensive and interesting examples which are particularly useful for the practicing engineers and students. Applications of computer-aided design and simulation are also presented. As such, it brings new way of understanding electrical power in a different perspective.
