THE CHALLENGE I Electricity power supply reliability, stability and increasing maintenance cost of
MV / LV transformers substations and transmission / distribution grids, are considered as major challenges that power utilities and private operators are facing today. Coupled with the fast transformation of electrical grids into smarter networks and in some cases into "micro grids", the electricity market is in a constant and intensive search for innovation and disruptive solutions.
Some critical failure points that cause unexpected power supply interruptions and require costly maintenance, are MV / LV facilities located near the end customer facilities, transmission & distribution substations, as well as transformers interfacing renewable energy sources to the existing grid. Cast resin dry transformers are considered a weak point in the chain, and are growing in numbers. Costs and other implications associated with a failed electrical distribution infrastructure could potentially be immense, critical and even disastrous.
OUR SOLUTION I An innovative, non-invasive, "IoT" system integrated with a Command & Control S/W, designed, by monitoring the phenomena of Partial Discharge (PD), to detect and measure in real-time developing insulation degradation faults in their very early stage. The common denominator of LV, MV and HV equipment is that one of the main failure mechanism and one of the most difficult to detect on time – in many cases age related – is appearance of electrical spikes due to defects or contaminations in the insulating material. This can lead over time to total equipment failure. The basic concept of our disruptive IoT system is detection and analysis of the Electro Magnetic (EM) emission generated by these discharges to continuously assess the equipment health.
Our technology has already been validated for MV cast resin dry transformers, which are the most sensitive and least reliable transformers type. Their number is increasing fast as they are environmentally safer!
Our competitive edge:
Noninvasive - no need for shut down / retrofit for sensors installation
Indifferent to equipment type: Manufacturer, age, model, etc.
Full integration with centralized Command & Control system
Complies with the smart grid trends of Remote Sensing, Internet-of-Things (IoT) and Actionable Big Data
Superior cost performance ratio
