ProductsMDD3000T Intelligent On - line Monitoring System for Transformers
MDD3000T Transformer on-line monitoring system is an online dynamic integrated transformer fault diagnosis system, composed of on-line monitoring and fault diagnosis. The on-line monitoring section includes basic units such as dissolved gases and micro-water in the oil, dielectric loss and partial discharge of the casing, and can expand the core ground, winding deformation, temperature load and switch input interface (cooling fan, oil pump, gas relay) Such as online monitoring. Fault diagnosis part includes fault diagnosis module, fault qualitative and positioning diagnosis module, fault severity and development trend analysis module, fault hazard assessment module and maintenance strategy module.
