CURRENT MEASUREMENT DEVICE, TEST DEVICE, AND COAXIAL CABLE AND ASSEMBLED CABLE USED FOR THEM

摘要

There is provided a current measurement device for measuring current to be measured and flowing between a first measurement terminal and a second measurement terminal. The device includes: a plurality of primary coils each having one end electrically connected to the first measurement terminal and the other end electrically connected to the second measurement terminal; a secondary coil generating voltage indicating the current to be measured, according to the current to be measured and flowing in the primary coils; and coaxial cables respectively corresponding to the primary coils and each having a signal line for electrically connecting one end of a corresponding primary coil to the first measurement terminal and a shield. Each of the coaxial cables includes: a signal line; an insulation layer coating the signal line; a first shield having a tape-shaped conductor wound around the outer circumference of the insulation layer; and a second shield composed of a conductor arranged on the outer circumference of the first shield.
