Electromagnetic compatibility requirements in underground coal mines
1 Scope
This document specifies the electromagnetic compatibility requirements for electrical equipment in underground coal mines and describes the corresponding test methods.
This document applies to the limit measurement of electromagnetic environment in underground coal mines, and to the measurement of operating frequencies in underground coal mines within the range of 0Hz to 400GHz.
Electromagnetic compatibility design, manufacturing and inspection of electrical equipment and its downhole installation.
This document covers the emission requirements for radio frequency interference in the 9kHz~6GHz frequency band.
This document covers the immunity requirements for underground electrical equipment in coal mines operating in the frequency range of 0Hz to 400GHz.
