As digital field instruments proliferate in smart substations—SF₆ density transmitters, arrester leakage monitors, oil temperature/level gauges—RS485 has become the backbone of data collection for GIS/AIS gas-density and auxiliary equipment monitoring. For more information on ODES communication and digital-instrument solutions, visit www.odes-electric.com . But with more instruments come new challenges: More meters → longer cable runs → mixed series/parallel topologies → hig

As smart substations adopt unified architectures for SF₆ density monitoring , arrester leakage measurement , and other digital field instruments, RS485 remains the backbone of data acquisition. For more on ODES communication and secondary-system solutions, visit www.odes-electric.com . In real GIS/AIS environments, RS485 must withstand long cable routes , harsh electromagnetic interference , and strict reliability requirements . The engineering challenge is clear: how

In most substations, temperature data for transformers still hides behind the control room screens. Oil, core, and winding temperatures — the “three thermometers” that reveal a transformer’s true condition — are often invisible at the equipment itself. Operators walk back and forth between panels and SCADA terminals just to confirm if things are running hot or cold. In regions like Inner Mongolia, Gansu, and Xinjiang , where on-site staffing is essential, maintenance teams
