G01R 27/18 Measuring resistance to earth
Introduced: September 1968
Full Title
Full titles differ between systems:
Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring real or complex resistance, reactance, impedance, or other two-pole characteristics derived therefrom, e.g. time constant > Measuring impedance of element or network through which a current is passing from another source, e.g. cable, power line > Measuring resistance to earth
Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring real or complex resistance, reactance, impedance, or other two-pole characteristics derived therefrom, e.g. time constant (by measuring phase angle only G01R25/00) > Measuring impedance of element or network through which a current is passing from another source, e.g. cable, power line > Measuring resistance to earth
