SSERemote Telemetry UnitSSE RTU Telemetry Systems…40-20 Years Ago
  • Rural Pumping Schemes – Controlled by hand
  • Urban Schemes – Controlled by Relay Logic & Instrumentation
  • Very Basic Telemetry Systems – Hard Wired with Mimic
  • Radio Telemetry – Starting to emerge for remote control.
  • …15 to 20 Years Ago
  • Demand for Operational Function – Alarms & Remote Control
  • Slow Radios (300 Baud) Installed – Limited Data Throughput
  • “Cable Replacer” Type Telemetry System
  • Control – Relay Logic/Basic PLC
  • Small Amount of Data – Mainly Basic Alarming & Limited Control
  • Master Station – MainlyMimic Panels & DOS Based SCADA
  • Typical Telemetry Network – Then! Scada Application Evolution of Technology
  • Driven by two main influences
  • From Client Side (Pulling forces):
  • Plants and distribution networks got more complex.
  • The demand for more information at a quicker rates.
  • Better / Faster service delivery.
  • From Technology offerings (Pushing forces):
  • New technologies offer better and smarter solutions
  • Faster processing power.
  • More robust communication networks.
  • Modern RTU’s
  • Compact – more I/O with smaller footprint
  • Connect to all wide area networks – compatible with new IP based networks
  • Intelligent – PLC Based processing capabilities
  • OPC Compliant Software – open standard for industrial applications
  • Remote Diagnostics – Network wide fault finding and configuration tools
  • Support for IED’s – protocol support for intelligent devices
  • Protocol Standardization
  • SSE Design Philosophy
  • Client Requirement driven.
  • Technology driven.
  • Follow well established engineering practises.
  • Hardware & Software are modular in design.
  • To design products that are:
