Transformer Dryout System Controller
The Transformer Dryout System Controller is an intelligent control unit designed to manage and automate online transformer moisture removal during energized conditions. Integrated with PTss Transformer Dryout Technology and the TIMES (Transformer Insulation Moisture Estimation System), it continuously monitors insulation moisture (%M/DWi) and initiates dryout operations automatically. The controller ensures safe, efficient, and unattended transformer drying while preserving oil quality through a non-intrusive oil circulation process.
Features
Intelligent Dryout Control – Automatically manages transformer dryout based on real-time moisture levels
TIMES Moisture Monitoring – Continuously estimates Moisture to Dry Weight of insulation (%M/DWi)
Automated & Unattended Operation – Triggers moisture removal without manual intervention
Non-Intrusive System Management – Controls oil circulation without heating or vacuum processes
Enhanced Transformer Reliability – Ensures optimal performance while maintaining oil integrity
