Measuring resistance to earth

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

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

CPC:

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

No child classifications to compare. This is a leaf node in both IPC and CPC.
