Electrical and electronic equipment are designed and built to operate satisfactorily under specified power quality and electromagnetic environment. They may malfunction or degrade in performance when operating beyond the stipulated power quality and EM environment. Electromagnetic compatibility (EMC) describes the ability of electronic and electrical systems or components to function correctly together. A system or equipment is electromagnetic compatible if it satisfies three criteria:
1. It does not cause interference to other systems;
2. It is not susceptible to emissions from other systems;
3. It does not cause interference to itself.

In the case of mission-critical control and signaling equipment, functional safety depends on the system or equipment operating correctly in response to its inputs. If the input signals are corrupted by electromagnetic interference (EMI), disastrous consequences may occur. EMC standards are used to ensure adequate availability of equipment and system functionality, with different standards developed to suit the wide variety of EM environments.

This one-day seminar will examine the fundamentals of EMC and the impacts of EMI on functional safety. Installation and mitigation guidelines to achieve EMC will be illustrated with particular reference to IEC610000-5 series of standards. The key topics include:
• Fundamentals of EMC
• Functional safety
• Cabling guidelines
• Earthing and bonding design
• HEMP and lightning protection concepts
• Protection against conducted disturbances
• Protection against radiated disturbances


Er. Professor Dr. Lock Kai Sang

Dr. Lock is a Professor at Singapore Institute of Technology (SIT) and concurrently an Adjunct Professor at Singapore University of Technology and Design (SUTD). He has a unique blend of practicing and academic experience acquired through a career equally split between the industry and the academia. As a teacher and trainer, his key strength is the fusion of practical examples with fundamental principles.

He is a Board Member of the Professional Engineers Board, Singapore and a Past President of the Institution of Engineers, Singapore. He is well-versed with standards and codes of practice and was the Chairman of Singapore Standards Council for 6 years, actively contributing to the promotion and establishment of Standards and Codes of Practice in Singapore. He is a Fellow of Academy of Engineering, Singapore, Honorary Fellow of ASEAN Federation of Engineering Organizations and Senior Fellow of ASEAN Academy of Engineering and Technology.

He received his BSc (1st Class Honours) in Electrical and Electronics Engineering in 1975 from the University of Strathclyde, UK. He completed his Ph.D. degree at the same university in 1979 researching on the design optimization of electrical machines. He joined the National University of Singapore as a lecturer in 1980 and was the Head of its Power and Machines Division, Department of Electrical Engineering, when he left in 1997 to set up his consulting practice. He has authored over 200 consultancy reports, mainly in power quality and reliability, EMC, lightning and surge protection, failure analysis, and design for mission-critical power system. After 19 years in consulting practice, he returned to the academia in 2016 as a Professor at SIT.

He is the co-author of the book “Grounds for Grounding: A Circuit-to-System Handbook” published by IEEE/John Wiley in 2010.
