Learning track
High Voltage Engineering
Insulation coordination, high voltage equipment and testing fundamentals.
Insulation & Breakdown Basics
How dielectric breakdown actually happens, Paschen's law, and why sharp edges are the enemy of high voltage design.
7 min readDielectric Materials
Gas, liquid and solid insulators — SF6, oil, porcelain, polymer and XLPE — and why the right choice depends on the application.
7 min readInsulation Coordination & BIL
How equipment insulation strength is deliberately matched against protective devices, using the Basic Insulation Level standard.
8 min readOvervoltages: Lightning & Switching Surges
Where transient overvoltages come from, and why they travel as waves that can double in voltage at reflections.
7 min readSurge Arresters
How metal-oxide varistor arresters clamp overvoltages, and why their placement matters as much as their rating.
7 min readHigh Voltage Testing
How withstand and partial discharge tests prove equipment actually meets its insulation rating before installation.
7 min readGIS & HV Equipment
Air- vs. gas-insulated switchgear, the core equipment in a substation, and how every earlier lesson shows up in real hardware.
