Analysis of Power Quality Monitoring and Equipment Selection for Low Voltage Side of Large Capacity Main Transformers
In recent years,the power supply method of 220 kV substations using 10 kV on the low-voltage side to directly supply loads to users has been promoted,which has brought about practical problems such as high working current,high short-circuit level,high cost and loss of the low-voltage side incoming equipment of the main transformer,making selection more difficult.This article analyzes the existing problems and provides several feasible solutions.
