Underground Cable FPIs Fault Passage Indicators for Underground Cable Systems Cable fault detection Our FPIs for underground HV cable networks provide versatile, fully configurable, overcurrent and earth fault detection. We offer options for both communicating and local earth fault indication. Visibility of fault passage enables the control room to identify the faulty section of network and coordinate local switching to isolate the fault and restore supplies to customers more quickly. FPIs are offered with range of power supply options to suit your application. Our battery powered FPIs provide up to 15 years of maintenance-free operation, or for more data-intense applications, power can be sourced from the substations auxiliary AC or DC supply. Control room visibility Our NX-series of devices offers built-in RTU functionality and 4G communications (with 2G failover). The NX-series can deliver a native DNP3 link direct to the control room as well as over-the-air firmware updates and configuration management from iHost™. With options for directional (using available voltage input terminals on the switchgear) or non-directional fault passage indication, load current monitoring, power flow detection, twin earth fault indication, USB and Bluetooth local communications, and much more, the NX-series is a key component of your network monitoring system. Local fault indication Our F-series devices offer core fault passage functionality and is the FPI of choice for many utilities. Designed to be installed at switching points on the distribution network, local indication is provided via hyper-bright LEDs. The devices can also be connected to a local distribution automation RTU via the output contact, to alert the control room to fault events on the network. Our F-series products are compatible with 1A secondary CTs as well as our flexible retrofit CT solutions. They can be offered as a directional FPI, subject to suitable voltage input terminals on the switchgear. Get in Touch Contact Us

Our integrated datastore has evolved to meet the changing needs of iHost users and the manufacturers of field devices which generate the data we look after. It has been designed to store many billions of values using a highly optimised and compressed time-series storage format . Providing access to the data is a separate challenge and something we invest a lot of software developer time and effort getting right. iHost includes a suite of dashboard analytics and visualisation tools to transform the time-series data into useful information. Deployment options Cloud hosted On-premises - with high availability options Ruggedised hardware local monitoring and control It's your data We have always been committed to making access to data as simple and open as possible (albeit behind firewalls on a secure network). Whilst we aim for iHost to provide users everything they need to interact with data collected from field devices we realise there may be times when this isn’t the only approach. So if you want to build your own reports, design something special for use on smart phones or tablets or even build an entire analytics application you are free to do so.

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

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.
