The Only Solution to Resolve Urban IDC Electromagnetic Field Issues
Hello everyone, and welcome. The topic of today's lecture is the truth behind data center (IDC) electromagnetic fields (EMF), along with technical and social solutions for an issue that has recently surfaced as a national concern. First, where within a data center are electromagnetic fields generated the most? Many people immediately think of the server racks in the computer room. However, the true primary sources are the switchboards, transformers, and Uninterruptible Power Supply (UPS) areas where massive amounts of extra-high voltage electricity enter the facility. In contrast, the servers themselves are housed in grounded metal chassis that act as Faraday cages, nearly completely blocking high-frequency EMF and electric fields. The real issue lies in the 60 Hz extremely low frequency (ELF) magnetic fields passing through the power grid. A 60 Hz alternating current (AC) creates a structure where time-varying electric and magnetic fields continuously induce each other as they p...
