Basic Information
Brand:GE
Product Type:Online Transformer Monitoring System
Enclosure:NEMA 4X(IP66),cast aluminum,powder-coated,dimensions approximately 315 x 219 x 196 mm.
Weight:Approximately 9 kg
Power Supply:Universal 100-240 Vac±10%,47-63 Hz,maximum 650 VA
Technical Parameters
Measurement Range:0-100%relative humidity(%RH)for humidity;0-2000 ppm(volume/volume,hydrogen(H2)equivalent)for gases.
Accuracy:±2%relative humidity(%RH)for humidity;±10%±25 ppm(hydrogen equivalent)for gases.
Repeatability:2%relative humidity(%RH)for humidity;better than±5%or±5 ppm for gases.Gas Relative Sensitivity:Hydrogen(H2)is 100%;Carbon Monoxide(CO)is typically 15±4%;Acetylene(C2H2)is typically 8±2%;Ethylene(C2H4)is typically 1.5±0.5%.
Response Time:10 minutes for sensor response(90%of step change).
Communication Interface:One local isolated RS-232 serial port,one remote isolated RS-485 serial port,supporting DNP3 protocol(serial or TCP/IP);an expansion connector is also available for connection to Ethernet 10-100BaseT cards,analog modems,etc.
Product Features
Real-time Monitoring:Monitors the content of fault gases and moisture in oil,providing real-time data and alerts to help users identify potential problems.Sensor Options:Available with either a”hydrogen-only”or”combined gas”sensor.The combined gas sensor is 100%responsive to hydrogen and also exhibits some sensitivity to carbon monoxide,acetylene,and ethylene.
Model Calculation:Based on IEEE standards and field experience,built-in transformer mathematical models,such as MVA models,winding hot spot temperature models,and insulation aging models,transform sensor input data into useful real-time information,providing further insight into the overall health of the transformer.
Convenient Communication:Multiple communication options and protocols,including support for Modbus and DNP3.0,facilitate integration with SCADA or DCS systems for remote monitoring and management.
Self-Diagnostics:The entire system features self-testing and self-diagnostics,automatically performing self-tests every 15 days.Detected faults(including power failures,oil valve closures,and sensor failures)trigger service alerts.
Easy Installation:Installation is via a single valve,eliminating the need for additional pumps,moving parts,or piping.Applications:Suitable for various power transformers,including autotransformers,distribution transformers,reactors,etc.,as well as transformers in industrial plants,which can reduce the risk of process interruptions due to power outages and minimize costly downtime.
