G01R 11/48 Meters specially adapted for measuring real or reactive components; Meters specially adapted for measuring apparent energy
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Electromechanical arrangements for measuring time integral of electric power or current, e.g. of consumption > Meters specially adapted for measuring real or reactive components; Meters specially adapted for measuring apparent energy
CPC:
Electromechanical arrangements for measuring time integral of electric power or current, e.g. of consumption (monitoring electric consumption of electrically-propelled vehicles B60L3/00) > Meters specially adapted for measuring real or reactive components; Meters specially adapted for measuring apparent energy
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
