Abstract
On-line insulation monitoring schemes for high voltage grid electric equipment are discussed, and modular designs of object-oriented on-line monitoring electric equipment and their parameters are suggested. The insulation properties of electric equipment are judged by monitoring medium consumption (tan δ) of capacitance equipment, resistance current of zinc oxide lighting arrester, core current of transformer, and content of gas in transformer oil.
