Title: Measurement resistance or shunt for current measuring - has inductive components in measurement and auxiliary paths for frequency independent measurement
Inventor: SPITZENBERGER CARL
IPC: G01R1/20
Filed: 1990-07-25
Abstract: A measurement resistance or shunt for current measurement has a resistive path between two connection points for input and output of the measurement current. The path contains a real and inductive component with an inductance (LS) in series with the real resistance (RS). A measurement voltage proportional to the measurement current is tapped from two measurement connections (4,5) to an auxiliary resistance in a series circuit also contg. an inductance and connected in parallel with the measurement path.  The ratio fo real resistance to auxiliary resistance equals that of measurement to auxiliary inductance. ADVANTAGE - Enables measurement voltage proportional to measurement current to be achieved which is independent of frequency.
