Why arc flash studies belong in every substation design
An arc flash study is not paperwork. It defines PPE, labelling and protection settings that decide whether a fault becomes an incident.

Engineering notes from the field
Short, practical articles on power quality, protection, digital substations and energy management — written by the engineers doing the work.
Power Quality
Harmonics in foundries: what induction furnaces really do to your network
Melting loads distort the supply in predictable ways. Here is how we measure, model and mitigate them without oversizing equipment.
