For e.g., the scope and the requirements for a risk-based approach for the automotive domain is discussed in detail in. In many industries involving complex systems, the need to adopt a risk-based EM engineering approach have already been identified. How are various industrial domains preparing to adopt a risk-based approach? So, a possible solution is that, in addition to the compliance to the current standards, it would also be necessary to perform a comprehensive risk assessment and implement risk mitigation measures to avoid any unacceptable consequences to the stakeholders. However, due to limitations on the budget for money, time, and equipment available for system immunity and emissions tests, it is impracticable to test a lot more than what is currently being done by the system manufacturers and component suppliers. 1) arising from the EMC issues that are identified later during the system development process. other consequences can be loss of money due to launch delays (see Fig. In addition to compromise of system attributes like safety, security etc.

Of course, these are only some of the reasons to say that the rule-based approach, which currently prescribes compliance to relevant EMC standards and regulations, is possibly inadequate for complex systems. the maximum test level is not necessarily the worst etc.

ageing is not considered by normal immunity testing.the effects of the physical environment are not considered by normal EMC testing.normal EMC test methods are designed for accuracy and repeatability, and not to simulate real life.only one EM disturbance is tested at a time.Several experts and scientists in the EMC domain explain why the current rule-based EMC testing approach is inadequate. For complex systems, electromagnetic compatibility is one of the important aspects to be achieved, such that potential hazards due to electromagnetic interference (EMI) compromising system attributes like safety, security, reliability etc., are avoided. Compared to their former versions, the later versions and the newly designed systems are increasingly electrified, connected, and automated, resulting in an increase of complexity and lack of system knowledge. In many domains, such as transport, medicine, defence etc., technological growth has enabled the implementation of advanced features and functionalities in a wide range of complex systems, such as road vehicles, medical equipment, marine vessels, aircraft etc. First, why is a change from the current rule-based approach necessary? And then, how are various industrial domains preparing to adopt a risk-based approach? Why is a change from the current rule-based EM approach necessary? I continue this discussion by answering two questions. In this blog, I have discussed something similar to that of the news I just mentioned, but in the context of bringing changes to the current electromagnetic compatibility (EMC) practice of using a rule-based approach to a risk-based approach. Cool right! Looking forward the see them with a CHANGE, FOR GOOD. Some good news, Norway’s Smøla wind farm has recently found out that the number of birds colliding with wind turbine blades can be reduced by almost 70 percent of simply by painting one blade of a wind turbine black. Hello reader, at the time of writing, I am doing my second year as a PhD student in the UK and it is still a nation-wide lockdown due to Covid-19, UGHHH!

A necessary change from the current rule-based EMC approach!
