Between 2012 and 2017, ModemTec laid the technological foundations for its leadership in Power Line Communication (PLC) — years that were less about buzzwords and more about building reliable, field-tested solutions. These early years saw: By 2017, we weren’t just testing in labs — we were deploying across critical infrastructure and proving that communication over […]

Back in 2012, ModemTec was laying the groundwork for what would become our flagship solutions. Early lab demonstrations focused on: By 2017, these prototypes had matured into field-deployable pilot systems: This formative period shaped our core philosophy: iterate fast, test thoroughly, build reliability first—principles that still guide PD Doctor today. 👉 Explore the full timeline […]

In recent months, Europe has experienced a series of large-scale power disruptions that have revealed critical vulnerabilities in the stability of electrical infrastructure. From the widespread blackout across the Iberian Peninsula to the recent outage affecting the London Underground, these events highlight the urgent need for smarter, real-time monitoring of grid components to prevent failures […]

In March 2025, a devastating fire at the Hayes Substation in West London resulted in a massive power outage that disrupted operations at Heathrow Airport, grounding over 1,000 flights and causing significant inconvenience and economic damage. This incident not only brought travel to a standstill but clearly illustrated the critical need to proactively ensure the reliability […]

If we are talking about partial discharges, there are two different types of diagnostics from the proper diagnostic action point of view. If the object under diagnostics is out of order, we talk about off-line (or trial) diagnostics. If the object is in operational order, we talk about on-line (or functional) diagnostics. Due to the fact, that very often, there […]
