Abstract: Introduction was made to the experimental online monitoring work of distribution transformer in certain power supply company. Via rectifying and reform of the applied analysis and abnormal condition, the technology and management problems were solved, where the fractional load, heavy load, three-phase load unbalance, low voltage and high voltage troubled the distribution transformer and they had impacts on the grid safety, reliablility and economic operation. The running condition of this distribution transformer was brought into electricity information collection system management to expand the functions of the electricity information collection system further and to realize the good effect for one system with multi-term management functions.
Key words: distribution transformer; online monitoring; experimental unit; applied analysis
