Dangerous effects and protective measures against electromagnetic disturbances when an Internet data centre is co-sited with a high-voltage substation (Study Group 5)
This Recommendation specifies calculation methods for dangerous effects@ tolerance limits of dangerous effects@ tolerance limits of electromagnetic effects from a high-voltage substation@ distance requirement and protection methods@ protective measures@ as well as requirements for power frequency magnetic field immunity of servers when an Internet data centre (IDC) is co-sited with a high-voltage substation. This Recommendation discusses co-sites for an IDC and a high-voltage substation while taking into account proximity@ the co-earthing network@ and shared accommodation. This Recommendation is applicable to IDCs and large communication centres co-sited with highvoltage substations. It is possible that this Recommendation may not apply to small Internet data sites.
