Intermediate relays rarely take center stage in substation design, yet they directly determine   wiring quality, maintainability, EMC robustness, and long-term reliability   in both primary and secondary circuits. For a complete overview of ODES relay and control products, visit   www.odes-electric.com . Leveraging its protection-relay engineering background, ODES developed   three plug-in relay families   to cover the full range of substation and industrial applications: RT

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
