Intermediate Course On Railway
Applications On EMC
Objective
To train the participant on the dynamics of electro magnetic interference and their mitigations in railway applications
Duration & Course Accessibility
The course is of 12-hour durations delivered through three 4-hour sessions.
Course is delivered by Mr Stuart Charles, Intellex’s tutor, delivered live remotely through MS Teams sessions.
Why one should attend
The course has been designed to demonstrate dynamics of Electro Magnetic Interference and how mitigations reduce its impact. By understanding the dynamics of EMI engineers can design EMC compliant designs, know how to test to detect any EMI as well as to understand the sources and risks of EMI in a railway environment.
Who should attend
The course is written for
engineers and managers who want to understand the risk, sources and dynamics of
EMI is detail to ensure that EMC is successfully designed into a project. Since
this course simplifies the concept of EMC this is also suitable for railway
operators and infrastructure regulators.
