How can the limitations of coaxial switches be overcome in smart grid applications

Optimizing Coaxial Switches for Smart Grid Applications

A hybrid architecture approach can overcome coaxial switch limitations by leveraging their RF strengths while addressing power system requirements through targeted design modifications.

  • Frequency Segregation: Use coaxial switches exclusively for RF sensing/data routing while employing PLC/Ethernet for power control. Modulate signals via RF carriers when temporary conversion is needed.
  • Power Segregation: Decouple low-power RF functions (IoT sensors) from high-power tasks handled by solid-state relays or circuit breakers.
  • Ruggedization Upgrades: Deploy IP68-rated connectors with thermal management. Implement dual-path redundancy (coaxial + Ethernet) for critical data.
  • Cost Optimization: Limit coaxial use to high-RF zones (substations) while using PLC/fiber for grid-wide control.
  • Signal Enhancement: Apply DSP error correction and ML-based predictive maintenance to improve reliability.
Implementation Example: In smart substations, coaxial switches route RF sensor data from equipment monitors while a separate IEC 61850 system controls circuit breakers - each optimized for their specific frequency and power domain.
By treating coaxial switches as RF/data enablers rather than power control tools and integrating them with PLC/fiber systems, smart grids can leverage their precision in sensing while relying on specialized power electronics for control. This hybrid approach optimizes performance across diverse grid environments.
