Abstract

To validate the effectiveness of different on-line monitoring devices for power transformers

a state emulation platform was constructed.The architecture and working principle of the platform are described

and the methods for realizing gas configuration

oil heating

partial discharge

and core grounding current are given.Then different on-line monitoring devices for transformer were fixed on the state emulation platform to test their reliability.Experiments demonstrate that this platform can emulate the state quantities of a transformer for validity check of the on-line monitoring devices.
