Description
technical field [0001] The application relates to the technical field of electric energy metering, in particular to a device for collecting and monitoring broadband electric parameters of a 10kV distribution network. Background technique [0002] my country's 10kV distribution network is responsible for almost all power consumption tasks. In order to meet the electricity demand, the construction scale of 10kV high-voltage power grid has greatly increased compared with the past. There are more and more nonlinear loads in the power system, such as: electric traction locomotive traction, iron and steel metal smelting electric arc furnace, chemical production equipment, household appliances and other power electronic devices, etc., making the power quality of the power system load and power consumption more and more The worse and more complex (such as: harmonic increase, dynamic distortion, power factor change, low voltage, heavy overload phenomenon, etc.); in addition, as more ...
