A penetration type current transformer, etc. is attached to the conductor to be measured of the equipment,
It supplies a current signal for driving an ammeter, a relay, and the like. In addition, for the purpose of lightning protection of power transmission and distribution equipment, an impulse current flowing through a conductor to be measured is observed by a Rogowski coil in an observation device for lightning surge or the like generated.

煩雑であると危険である。However, in the power receiving and distribution equipment, a wide variety of devices must be installed in a compact manner, and the location and position for mounting the current sensor have many space restrictions. Further, in the current sensor, unless the conductor to be measured is arranged at the center position of the ring shape, the magnetic flux linked to the ring-shaped coil is not uniform, and the measurement error of the current increases. For this reason, when mounting the current sensor, adjustment must be made so that the conductor to be measured is located at the center of the current sensor, and this requires a very cumbersome operation in combination with the above-described space restrictions. In particular, the work of attaching the current sensor to the lightning rod near the top of the power transmission tower and the ground wire of live equipment on the distribution pole is
It is dangerous if it is complicated.
