Remote Monitoring (Transformer)
Online diagnostic systems providing real-time transformer condition data including DGA, temperature, and partial discharge via SCADA.
Remote monitoring systems provide continuous, real-time transformer condition assessment via online sensors communicating to central SCADA/cloud platforms. Key parameters: dissolved gas analysis (DGA), hot-spot temperature, moisture, bushing capacitance/tan-delta, partial discharge.
Enables predictive maintenance: trend analysis detects developing faults before Buchholz trip. Smart O&M platforms provide AI-driven diagnostics and remaining life estimation.
Communication: IEC 61850, Modbus TCP, DNP3.0. Edge computing for local analysis; cloud for fleet management.
QDTB offers integrated monitoring packages with all oil-immersed transformers above 50 MVA. Smart O&M solutions include commissioning and support. Contact us for monitoring specifications.
