Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a low-voltage power distribution power parameter monitoring device. Background technique [0002] With the increasing power consumption of industry, agriculture and residents, the investment and construction of the power industry have also increased, but it is still difficult to meet the growing demand. With the continuous increase of power grid capacity, the structure of power grid devices has become more complex, and various nonlinear loads such as frequency converters and rectifiers are widely used in China. These nonlinear and unbalanced loads make the power supply safety factor of the power grid worse. , has brought great harm to society. In order to ensure the safe operation of the power grid and understand the operating status of the power grid, it is necessary to monitor various parameters of the power grid in real time, and to send various parameters to the disp...
