Cable Sizing Calculator

Check current-carrying capacity and voltage drop for NYY copper and NAYY aluminium cables in single-phase and three-phase motor / general feeders.

  • Single-phase / three-phase selection
  • Input by kW, kVA or A
  • NYY Cu / NAYY Al selection
  • Recommend a cable or verify your selected cable

Power Factor Correction

Run quick preliminary calculations for load correction, transformer fixed compensation and step distribution.

  • Load correction by kW or kVA
  • Fixed kVAr pre-selection by transformer rating
  • 12 / 18 / 24 step distribution draft
  • Reactive and apparent power comparison

Transformer Center Calculator

Run transformer current, approximate short-circuit current and connection pre-checks for concrete compact substations and pole-mounted transformers.

  • Concrete compact / pole-mounted selection
  • Transformer full-load current
  • Approximate short-circuit current
  • Table 6 connection for concrete compact units, cable-sizing guidance for pole-mounted units
