SSE Remote Telemetry Unit SSE 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. SSE 10years,based in Pretoria,36 staff,Branch Cape Town. Manufacture Telemetry, Antennas,Import MDS Radios.

…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 – Mainly Mimic Panels & DOS Based SCADA SSE 10years,based in Pretoria,36 staff,Branch Cape Town. Manufacture Telemetry, Antennas,Import MDS Radios.

Typical Telemetry Network – Then!

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. Scada Application

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 10years,based in Pretoria,36 staff,Branch Cape Town. Manufacture Telemetry, Antennas,Import MDS Radios.

SSE Design Philosophy Client Requirement driven. Technology driven. Follow well established engineering practises. Hardware & Software are modular in design. To design products that are: Economical User friendly Open Compatible Expandable Always backwards compatible to older version RTU’s 7
