Cette application propose des calculettes électrotechniques telles que (Loi d'ohm, Puissance active, réactive, apparente, ICC Max transfo, Résistivité, Résistances en parallèle, Résistances en série, Convertisseur de signal 4-20mA 0-5V...) Et d'autre à venir... Calcul de section de câble ou courant admissible selon la méthode NFC 15-100 (Mode de pose, Température, Nombre de circuits...) Prise en compte de la chute de tension dans le calcul. Abaques sur les transformateurs de distribution immergés dans l'huile ou enrobés donnant des valeurs types telles que (Valeur de fusible de protection Amont, In, Icc, Ucc et pertes cuivre). Abaques courant admissible barres de cuivre et souple. N’hésitez pas pour tous commentaires ou suggestions d'amélioration, nous sommes à l’écoute de vos idées, afin de rendre cet outil le plus complet possible et devenir une référence pour les électrotechniciens.

Verdict
The clearest difference is in-app purchases: SHB Electric at none against CuCalc's 1. SHB Electric also leads on update cadence (every 10 days vs every 3 weeks) and device support. On price there is nothing between them.
