GIC-151Z电流传感器
品牌:美国 OSI
型号:GIC
类型:直流电流传感器(地磁感应电流)
产品描述DESCRIPTION
GIC系列传感器能够在交流电压较高的情况下测量直流电流。这使得能够准确测量电网上的地磁感应电流(GIC),以及光伏系统和逆变器中可能存在的直流分量。该设备在较宽的动态范围内运行,即使在较大的超范围后仍保持较低的精度。GIC固有的低残余效应消除了除极端情况外所有情况下的消磁需求。分芯外壳具有外加硬件和室外额定值,安装简单,无需中断电路。
GIC-xxxz transducers are able to measure DC currents in the presence of higher levels of AC. This enables accurate measurement of Geomagnetically Induced Currents (GIC) on power grids, and of the DC components potentially present in Photo-Voltaic system and inverters. The device operates over a wide dynamic range and maintains low-level accuracy even after a large over-range.The GIC’s inherently low residual effect eliminates the need to degauss in all but extreme circumstances. The split-core enclosure, with captive hardware and outdoor rating, makes installation easy and does not require circuit interruption.
