REFLEX ® Retrofit Distribution Automation for Ring Main Units Introducing the REFLEX system ® A revolutionary new product to help improve SAIDI (CAIDI, CML) performance, at the same time extending the useful life of existing switchgear. With the demands on electricity networks increasing, the need for “Productising” Distribution Automation and Remote Control was clear. Nortech developed the REFLEX system to make retrofit remote control safer, quicker and lower cost. A single product suitable for use on all the most common switchgear makes and models. ® Quick and Easy Deployment REFLEX is quick to install, really quick. A single team can retrofit multiple substations per day, with no need to operate live switchgear as part of the commissioning process. REFLEX enables widescale deployment of Distribution Automation in a fraction of the time, and at a fraction of the cost, of traditional alternatives. REFLEX units talk directly to the central SCADA / DMS system using industry standard SCADA protocols - no separate RTU needed. REFLEX fits on all common Ring Main Unit makes and models - making approvals, training, purchasing, logistics and maintenance simpler. ® ® ® ® Get in Touch Contact Us

Our Products Innovative monitoring and control technologies for electricity network and system operators RTUs and Smart Sensors The increase in embedded generation, changes in load patterns and adoption of electric vehicles are just some of the reasons that power flows, voltage profiles and constraints on the distribution network are becoming more complex and no longer match traditional models used by network planners and design teams. Taking action to keep the grid stable requires that operators have visibility of what is happening out on the network. Nortech technology components provide network and system operators the ability to see deep into the network beyond the reach of traditional SCADA systems.

PRE-FIX TM Real-time HV Pre-Fault and Post-Fault Location What is PRE-FIX ™ ? PRE-FIX is a HV network fault location solution which can locate and classify pre-faults and post-faults to within a few metres – fully automated, all in real time. Originally trialled as an OFGEM-funded, NGED-led NIA project, PRE-FIX was found to be effective on both overhead line and cable networks. PRE-FIX analyses data from network sensors (Power Quality Monitors, Disturbance Recorders and Fault Passage Indicators) and combines this with network information (network connectivity models, asset data and GIS data) all in real-time. Most Economical Solution By augmenting expensive primary substation instruments (PQM or Disturbance Recorders) with lower cost feeder monitors and network sensors, means a much lower instrumentation budget overall. Savings of up to 90% on instrumentation costs over alternative solutions can be achieved. Get in Touch Contact Us
