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.
Dielectric Materials
Gas, liquid and solid insulators — SF6, oil, porcelain, polymer and XLPE — and why the right choice depends on the application.
Insulation Coordination & Withstand Levels (BIL)
How equipment insulation strength is deliberately matched against protective devices — and how ANSI/IEEE BIL relates to IEC 60071 rated withstand voltages.
Overvoltages: Lightning & Switching Surges
Where transient overvoltages come from, and why they travel as waves that can double in voltage at reflections.
Surge Arresters
How metal-oxide varistor arresters clamp overvoltages, and why their placement matters as much as their rating.
High Voltage Testing
How withstand and partial discharge tests prove equipment actually meets its insulation rating before installation.
GIS & HV Equipment
Air- vs. gas-insulated switchgear, the core equipment in a substation, and how every earlier lesson shows up in real hardware.
