Case Studies regarding the integration of monitoring diagnostic equipment on aging transformers with communications for SCADA and maintenance

摘要

Valuable information from Monitoring and Diagnostics (M&D) equipment installed on aging power transformers help utility personnel operate and maintain critical infrastructure. M&D systems provide valuable on-line information from power transformers including gas in oil, internal hot spot temperature, insulation aging moisture content in winding insulation, bubbling temperature, and OLTC position tracking. This presentation reviews several methods of integrating M&D equipment to provide this information to SCADA and maintenance systems.
