Electrical Engineering Tools & Calculators
Free, practical tools for electrical and panel design in the UAE — power-factor (APFC) sizing, motor full-load current, cable voltage drop, kVA/kW/amps conversion, maximum demand and energy cost. Built by a Dubai switchgear manufacturer.
Power Factor (APFC) kVAR Calculator
Size the capacitor bank to correct your power factor and cut DEWA penalties.
Motor Full-Load Current (FLC) Calculator
Find a motor's full-load and starting current to size its cable, breaker and overload.
kVA / kW / Amps Calculator
Convert kVA to kW, kVAR and line current for 3-phase and single-phase systems.
Cable Voltage Drop Calculator
Check voltage drop along a copper or aluminium run against the ~4% limit.
Maximum Demand & Diversity Calculator
Turn connected load and a diversity factor into maximum demand and design current.
Energy Cost Calculator (AED)
Estimate the monthly and yearly running cost of a load from its kW and tariff.
Practical calculators for panel and switchgear design
Standards-based math
Each tool uses standard IEC engineering formulas — full-load current, voltage drop, kVA/kW/amps, diversity and power-factor correction — so the numbers line up with your design calculations.
Sized, then built
Use the results to scope a job, then send us the requirement: we design, build and test the distribution board, MCC, APFC or control panel to match — in our Dubai factory.
Free & no sign-up
Every calculator runs in your browser — no account, no download. Bookmark them and share with your team across the UAE & GCC.
