IPC: G01R15/20
Filed: 1988-12-12
Abstract: PURPOSE: To reduce impedance significantly by an arrangement wherein an unit disposed in a gap generates a signal proportional to the total sum of DC and AC low frequency components and an adder means generates a signal corresponding to the input current thus eliminating the need of compensating for the fluctuation of flux. CONSTITUTION: A separating means R separates the total sum Im of DC and AC low frequency components of a current I to be measured from the total sum ir of high frequency components of the current I and generates a first signal (Vr or Vad ) proportional to the total sum ir . An unit G disposed in a gap E generates a second signal Vi proportional to the total sum Im. An adder means Σ adds the first and second signals to generate a third signal proportional to the current to be measured.
