High Voltage Direct Current (HVDC) is transforming modern power transmission, enabling efficient, long-distance, high-capacity energy transfer. This article explains how HVDC works, why it is used, and why advanced condition monitoring is critical for reliable operation.
Articles & Case Studies
Modern wind turbines are complex electro-mechanical systems where power electronics, high electrical stress, and insulation integrity intersect. Understanding how turbines feed the grid helps explain why early electrical faults, including partial discharge, matter for reliability and fire risk.
As electricity demand accelerates worldwide, utilities are revisiting 765 kV EHV transmission lines as high-capacity “power highways,” enabling long-distance bulk power transfer while raising new technical challenges in corona control and insulation performance.
Partial discharge (PD) can emerge at any stage of a rotating machine’s life cycle, quietly degrading performance and reliability. Solar-blind UV imaging reveals these hidden discharges instantly, enabling early detection, stronger insulation design, and confident, PD-free operation.
Renewable energy is transforming today’s power grid, but reliable integration depends on flawless performance of substations, transformers, and transmission lines. Advanced inspection tools like OFIL’s UV technology help operators secure grid stability as renewable adoption rapidly accelerates.
Discover how Dynamic Ratings combined continuous PD monitoring with high-sensitivity solar-blind UV corona imaging to pinpoint degrading bushings—showcasing the critical role of optical UV diagnostics in strengthening early failure detection and preventing costly outages.
Utilities face growing pressure to make smarter maintenance decisions. Gridnostic’s Severity Diagnostic Methodology transforms vast inspection data into objective, prioritized insights—combining AI-guided condition analysis with asset impact context to help utilities focus resources where they matter most.
Switchgear plays a vital role in protecting and routing electrical power, yet it remains vulnerable to partial discharge. Detecting PD early—especially with UV imaging—helps utilities prevent insulation breakdown, avoid costly outages, and ensure long-term reliability of critical equipment.
Commissioning ensures new electrical systems start fault-free. OFIL’s solar-blind UV cameras reveal hidden corona and arcing, enabling immediate corrections. Establishing a clear baseline at commissioning safeguards reliability, reduces future failures, and provides lasting insight through Gridnostic-linked inspection records.
