EMC Regulations of Construction Equipment Vehicles in India : Challenges and Solutions

Requirement for Construction Equipment Vehicles (CEVs) in India is continuously growing as India being fastest growing country in the world in terms of Infrastructure. The technology in the automotive industry is evolving rapidly in recent times. Thus, with the development of new technologies, the challenges are also ever-increasing from an Electromagnetic Interference, Susceptibility (EMI/EMC) and Safety perspective. CEVs include various types of machines including Compactor, Wheel Loader, Crane, Paver, Truck Crane, Cement Mixer etc. EMC requirements of all these types are internationally governed by ISO 13766-1, 2. This paper provides insights about various considerations to be taken during EMC Tests of each type of machines. It also includes guidelines related to antenna positioning, reference point calculations, Narrow Band and Broad band considerations. It will also provide general EMC guidelines and precautions related to component selection and placement along with typical EMC Failures and its remedies. Considering CMVR requirement in India, AIS 160 (for Diesel Engine CEVs) & AIS 174 (for Electric Power Train CEVs) is already notified and above research will certainly help OEMs to mitigate their EMC problems at early stage and will smoothen their development cycle.
