We are gathering practical engineering tools for cable sizing, power factor correction, transformer centers and similar field decisions in this section. The aim is to make assumptions visible, support quick pre-checks and provide a stronger starting point for final engineering decisions.
Check current-carrying capacity and voltage drop for NYY copper and NAYY aluminium cables in single-phase and three-phase motor / general feeders. The output supports fast pre-design decision-making.
Run quick preliminary calculations for load correction, transformer fixed compensation, step distribution and reactive-ratio checks before panel design decisions.
Run transformer LV current, approximate short-circuit current and connection pre-checks for concrete compact substations and pole-mounted transformers.
