Hardware Design of Online Monitoring System for Power Transformer Malfunction

Article Preview

Abstract:

Power transformers are vital equipments in the grid and their reliability can affect the security of the grid directly. So it is always necessary to monitor the power transformers online. The study designed a multi-parameter online monitoring system for power transformer malfunction utilizing DSP and computer technology. The paper mainly introduced the design and component selection of online monitoring circuit for partial discharge, dielectric loss, gas component in oil and iron core's grounding current. The result showed that this system can diagnose most the malfunctions in power transformers with satisfactory property.
