Voltage Drop is a practical electrical calculation toolkit for electrical engineers, technicians, electricians, and students. Three tools in one: • VOLTAGE DROP CALCULATOR — Computes voltage drop for single/three-phase and copper/aluminum, and checks the result against your chosen 1.5%, 3% or 5% limit. It recommends the minimum cross-section that satisfies BOTH the voltage-drop limit and the current-carrying capacity. • CABLE SIZING — Finds the smallest cable cross-section required for your load and line, and lists the cable types available in that size. • CABLE CATALOG — Provides the technical features of common low-voltage cables (NYA, NYAF, NYM, H05VV-F, NYY, NAYY, NHXMH, N2XH, N2XH FE180), including current-carrying capacity tables per cross-section (in air / in conduit / in ground), right inside the app. FEATURES • Single-phase and three-phase systems • Copper and aluminum conductor support • 1.5% / 3% / 5% voltage-drop limit check with cross-section recommendation • "Suitable cables" suggestion after each calculation, with one-tap access to cable details • Cable technical-feature tables (including halogen-free cables) • Calculation history: save, reopen, delete • Works fully offline, ad-free • 9 language support PRIVACY The app does not collect any personal data.
