As society’s dependence on electricity increases, the issue of the quality of power supply and the elimination of unexpected outages comes to the fore. This is made possible primarily by diagnostics and its tools. The rapid development of diagnostics goes hand in hand with the increasing complexity of diagnostic systems and new technical possibilities in […]

🌟 ModemTec is proud to be a Gold Sponsor at the upcoming 2024 International Conference on Diagnostics in Electrical Engineering (Diagnostika24), hosted by the University of West Bohemia in Pilsen. We will showcase our cutting-edge Partial Discharge Online Monitoring System – PD Doctor, which plays a crucial role in enhancing the safety and reliability of […]

Power Line Carrier (PLC) communication uses the low-voltage distribution network. It is completely irrelevant what standard or proprietary protocol is used. Meter reading systems use the same frequency band and distribution system, which always has similar characteristics and behavior. What influences the effectivity of PLC communication? Among the influences that affect data transmission from e-meters […]

We were tasked to provide continous online partial discharge monitoring system, to enhance the safety and reliability of a vital energy distribution point in Poland. Site inspection led us to deploy the PD Doctor system within a 15 kV transformer station, and subsequent to a successful installation, a period of stable discharge activity was observed. […]

☕ 📰 Partial discharges (PD) represent a critical concern in railway traction systems due to their potential to degrade insulation, leading to equipment failure and safety hazards. Understanding the determination and influence of PD in these systems is crucial for ensuring reliable and safe operation.☕ 📰 How to determine partial discharges? 💻 Firstly, the determination […]

Partial discharge (PD) is a type of electrical breakdown that occurs when only part of the insulation between two conductors is damaged. This results in localized increase in electrical current, which can cause damage to the surrounding insulation. Partial discharge can occur in any type of electrical equipment but is most commonly found in high-voltage […]

Since the establishment of communication networks, it has been necessary to choose between centralised and decentralised solutions. However, there are not only two solutions – it is also possible to choose different levels of decentralisation. What level of decentralisation is suitable depends on a number of parameters. The main parameters include connectivity between different network […]

There are a few imperfections in contemporary smart systems currently being used in power engineering. The slowdown or halt in the installation of new smart systems (primarily smart electrometers) force us to ponder and analyse this situation. Unfortunately, we can clearly see that the proclaimed words ‘standardisation’ and ‘interoperability’ were merely a way to get control […]

In May 2016, there was an inconspicuous news item in the press about the beginning of consumption trading on the energy market. In other words: consumers will receive payment for allocated consumption. Unfortunately, this is one of the first, tangible outputs of the European Commission’s ’20-20-20 strategy’. The Challenge of Energy Investment The key question is, […]

IoT, sub-GHz, LPWAN… Everyone who is aware of contemporary trends in telecommunication technology and its evolution could not have missed these ‘magical’ abbreviations. All prominent manufacturers of microcontrollers, sensors, communication chipsets and their components offer some ‘IoT ready’ components. At first, it may seem the bells have tolled for PLC (power line communication) and that the future […]
