Electromagnetic compatibility (EMC) and why it is often ineffective

In theory, meeting the global standards for Emissions and Immunity protects a lift or escalator from electromagnetic interference (EMI) caused by outside sources and protects other equipment in a building by limiting the emissions generated by the vertical transportation equipment. Installation methods and aging often render EMC measures ineffective. EMI and its sources are identified, both proper and improper installation methods are detailed, and the degradation of EMC equipment over time are explained.
