Summary:PROBLEM TO BE SOLVED: To provide a method of built-in testing of an arc fault/transient detector.SOLUTION: A detector for detection of electrical arc faults or transients is integrated into or electrically coupled to an electrical power supply system. The detector is connected such that a simulated arc due to a test switch and a breaker switch is detected. The determination is made based on detected arc current and arc voltage magnitude and change rate, operation of the breaker switch, etc. 【課題】アーク故障／過渡検出器の組込み試験方法を提供する。【解決手段】検出器が電力供給システムに統合されたまたは電気的に結合された、電気的アーク故障または過渡を検出するための検出器を試験開閉器及び遮断開閉器による模擬アークが検出されるように接続し、検出されたアーク電流、アーク電圧の大きさ、変化速度、遮断開閉器の動作などにより判定する。【選択図】図１
