2 Outline Overview of TC 77: Scope, Structure, and Officers IEC Series (EMC Publications) Electromagnetic Environment Generic EMC Standards Generic Immunity Standards EMC and Functional Safety Recent Topics of TC 77 and Its Subcommittees 2

3 TC 77 Scope It is the task of TC 77 and its SCs to prepare standards, technical specifications and technical reports in the field of electromagnetic compatibility (EMC), with particular emphasis on general application and use by product committees and the electrical industry (Horizontal function). The scope covers the following aspects of EMC: Immunity and related items, over the whole frequency range: basic and generic standards; Emission in the low frequency range (f 9 khz, e.g. harmonics and voltage fluctuations): basic, generic and product family standards; Emission in the high frequency range (f > 9 khz): disturbances not covered by but in co-ordination with CISPR (e.g. mains signaling). 3

4 TC 77 Structure (1) TC 77: EMC Generic immunity standards, the description/classification of electromagnetic environments, installation measures, and functional safety SC 77A: Low frequency phenomena Low frequency phenomena (f 9 khz) SC 77B: High frequency phenomena High frequency continuous and transient phenomena (> 9 khz) SC 77C: High power transient phenomena To protect civilian equipment, systems and installations from threats by man-made high power transient phenomena including the electromagnetic fields produced by nuclear detonations at high altitude (High Altitude Electromagnetic Pulse (HEMP)) and sources of Intentional Electromagnetic Interference (IEMI) 4

8 Electromagnetic Environment (1) IEC TR Ed. 3.0 ( ) Environment - Description and classification of electromagnetic environments Working Group: TC 77/WG 13 IEC TR Introduces the concept of disturbance degrees and defines these for each electromagnetic phenomena; classifies into various location classes and describes them by means of attributes; provides background information on the different electromagnetic phenomena that may exist within the environment, and compiles tables of disturbance levels for electromagnetic phenomena that are considered to be relevant for those location classes. 8

9 Electromagnetic Environment (2) IEC TR Ed. 3.0 ( ) Environment - Description and classification of electromagnetic environments Maintenance Continuous updates of IEC/TR due to the likely future changes in the electromagnetic environment EMC issues related to electric vehicles, LTE, digital dividend and smart grid should be considered The conducted electromagnetic environment in the frequency range 2 to 150 khz should be examined more closely The description of electromagnetic environments in the IEC series shall be aligned in a better way 9

10 Generic EMC Standards Generic EMC Standards Emission Immunity Residential, commercial, light industrial environment IEC (CIS/H) Industrial environment IEC (CIS/H) Power station and substation environment Indoor equipment HEMP environment IEC (TC 77) IEC (TC 77) IEC (TC 77) IEC (TC 77) IEC (SC 77C) The IEC's Generic EMC standards are for products operating in a particular EMC environment but for which no specific EMC standards yet exist. They are in effect general and somewhat simplified EMC Product standards. ( 10
