变压器校准器gdhg - 206

数字 精度 自动

GDHG-206 CT/PT现场校验仪产品说明GDHG-206 CT/PT现场校验仪用于分析电流比例误差、角度误差、比例误差/角度误差为1%-200%电流的电流互感器和电压互感器。可直接测量CT/PT的匝数比和极性，实际二次负荷。该机型采用直流和交流供电，精度高，自动线性调节。采用高速可靠的数字处理模块。特点320*240液晶显示屏显示。单机完成CT/VT的误差测量，便于现场校准。现场校准CT/PT。无需标准CT/VT，电流注入器，升压器，电流/电压负载箱，控制单元和一次电流注入电缆。布线非常简单，大大提高了工作效率。内部有标准CT，匝数比与测试CT相同，精度为0.02级。 Anti-interference of power frequency electromagnetic radiation and series connection. Broad measurement range. It can measure both standard ratio and non-standard ratio CT. Direct analyzing the data if it is pass or fail. Measure standard CT or non-standard CT 1%-120% rule point error(angle error and ratio error). Measure standard CT or non-standard CT 1%-200% any point error(angle error and ratio error). One time testing and display error of upper limit burden and lower limit burden of CT. One time testing and display error at any actual burden of CT.
