    • Methods for measuring insulation resistance in a photovoltaic (PV) array may include partitioning the PV array into groups of PV panels, isolating a group of PV panels selected for an insulation resistance measurement from other groups of panels by setting bypass selectors on each PV panel in the PV array, and making an insulation resistance measurement for the selected group. If a measured value of insulation resistance for a selected group corresponds to an insulation problem in a PV array component, a separate measurement of insulation resistance may be made for each PV panel in the selected group. Insulation resistance measurements may be made accurately and rapidly for large PV arrays without disconnecting and reconnecting cables between panels. Measurements may be made at frequent, regular intervals to permit changes in insulation resistance to be detected before damage from dielectric breakdown occurs.
    • 用于测量光伏(PV)阵列中的绝缘电阻的方法可以包括将PV阵列分成PV组,将通过在每个PV面板上设置旁路选择器来隔离选择用于绝缘电阻测量的一组PV面板与其他组面板 PV阵列,并对所选择的组进行绝缘电阻测量。 如果所选组的绝缘电阻的测量值对应于PV阵列组件中的绝缘问题,则可以对所选组中的每个PV面板进行绝缘电阻的单独测量。 对于大型光伏阵列,可以准确快速地进行绝缘电阻测量,而不会断开并重新连接面板之间的电缆。 可以以频繁,规则的间隔进行测量,以在发生电介质击穿损坏之前检测绝缘电阻的变化。
