Dozens of PD Doctor installations across Europe have proven their high added user value and reliability for customers. They have detected degradation of existing lines, helped eliminate high interference on overhead lines, established the link between rainy weather and increasing partial discharge (PD) activity, for example, or helped save significant amounts of money by postponing […]

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 […]
