Transformer Monitoring System

• Detects incipient faults and assists in preventing failures and unplanned outages • Enables the condition based maintenance • Improves staff safety and environmental protection • Provides valuable data for a root cause analysis and an investigation in case of a failure event • Helps in optimizing transformer performance and enables better asset management (overloading, lifetime expectancy estimations) • Makes your transformer ready for the 'Smart Grid' Overview Transformers are one of the key and most valuable components in a power system. Equipping them with an on-line monitoring system is...

Monitoring functions Due to modularity any of the following functions may be included in the system: Bushings • Operating voltages • Overvoltages • Change of bushing capacitance • Tan delta /power factor • Loading current (single or three phase) Active part • Power (apparent, active, reactive) • Losses • Oil temperature (top, bottom) • Ambient temperature • Hot-spot temperature (calculation or fiber optic measurement) • Gas in oil (single or multi gas sensors) • Moisture in oil and paper • Paper insulation ageing and lifetime Partial discharges • Electrical, acoustic and UHF methods available On-Load...
