insulation and conductivity tests are part of the daily routine of the electrical engineers in mines, and to eliminate the inconvenience of having to carry two instruments around, the insulation resistance tester and conductivity tester have been combined into one instrument termed the insulation
in electrical and safety engineering, hazardous locations (hazloc, pronounced haz·lōk) are places where fire or explosion hazards may exist. sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. electrical equipment installed in such locations could provide an ignition source, due to electrical arcing, or high temperature.
electricity is the main source of energy used in coal mines, due mainly to the high efficiency and convenience by which it is passed along cables. it is a medium that must be used properly and with caution to enable safety to be maintained properly as open sparking, shock and fire are the main hazards which may be encountered when faults occur.
electrical equipment for hazardous gas areas is grouped as follows: a) group i – electrical equipment for mines susceptible to methane, and b) group ii – electrical equipment for all places with an explosive gas atmosphere, other than mines susceptible to methane. group ii
