Electromagnetical Environment and Safety for Large Sensitive Systems a New Approach and First Solutions

This paper presents the main considerations about the application of a new EMC concept on the electromagnetic compatibility studies and protections. This concept specifically adapted for large and complex systems called the "zero method". This method allows hospitals, computers, power, gas and petroleum plants etc... find quickly economic and technical good solutions against electromagnetic interferences made by lightning effects and industrial disturbances effects. The efficiency of these solutions is confirmed along ten years of operation.
