を直列に接続した閉回路において、二次励磁電源
の上記変流部側の一端と電流検出部の変流部側の
一端との間に抵抗を接続し、この抵抗の両端にか
かる電圧を分圧する任意の位置に増幅器の一端を
接続し、この増幅器の他の一端を上記二次励磁電
源に接続したことを特徴とする直流電流変流器。 In a closed circuit in which at least a current transformation section, a current detection section, and a secondary excitation power source are connected in series, there is a resistance between one end of the secondary excitation power supply on the current transformation section side and one end of the current detection section on the current transformation section side. A direct current current transformer characterized in that one end of an amplifier is connected to an arbitrary position that divides the voltage applied to both ends of this resistor, and the other end of this amplifier is connected to the secondary excitation power source. .
