DIFF Subgroup
G01R 21/07 in circuits having distributed constants (G01R21/09 takes precedence)
Introduced: July 1974
Title
Titles differ between systems:
IPC: in circuits having distributed constants
CPC: in circuits having distributed constants (G01R21/09 takes precedence)
Full Title
Full titles differ between systems:
IPC:
Arrangements for measuring electric power or power factor > by measuring current and voltage > in circuits having distributed constants
CPC:
Arrangements for measuring electric power or power factor (G01R7/12 takes precedence) > by measuring current and voltage (G01R21/08 - G01R21/133 take precedence) > in circuits having distributed constants (G01R21/09 takes precedence)
No child classifications to compare. This is a leaf node in both IPC and CPC.
