| description | PROBLEM TO BE SOLVED: To enhance resistance to DC magnetic deviation due a transient DC component by using an EI core, while making the core compact, and to maintain the exciting impedance by hybridizing the iron core of the EI core.SOLUTION: An input converter of a digital protection controller performing protection control of a power system is constituted of an input transformer for measuring the electrical quantity of a power system, and an input section for capturing the output from the input transformer. The input transformer consists of an EI core where the iron core is hybridized.
【課題】ＥＩコアを用いて過渡直流分による直流偏磁に対する耐性を向上させるとともにコアを小型化し、ＥＩコアの鉄心をハイブリッド化して励磁インピーダンスを維持する。【解決手段】電力系統の保護制御を行うディジタル保護制御装置の入力変換器であって、前記入力変換器は、電力系統の電気量を測定する入力変成器と、前記入力変成器からの出力を取り込む入力部から構成され、前記入力変成器は、鉄心をハイブリッド化したＥＩコアからなることを特徴する。【選択図】図１ |
