Developer Description
This app is essential for an electrician
Supported standards: IEC (International Electrotechnical Commission), CEI (Comitato Elettrotecnico Italiano), NEC (National Electrical Code), CEC (Canadian Electrical Code).
The application offers a wide range of calculations for the fundamental aspects of an electrical system, wiring diagrams, and formulas.
Main calculations:
Wire size, voltage drop, current, voltage, active / apparent / reactive power, power factor, resistance, Maximum wire length, Current carrying capacity of insulated conductors / bare conductors / busbar, Conduit fill, Sizing the circuit breaker, Admissible let-through energy of the cable (K²S²), Operating current, Reactance, Impedance, Power factor correction, Power factor correction of transformer MV/LV, Capacitor power at different voltage, Earthing system, Short circuit current, Conductor resistance, Calculation of the cable temperature, Power losses in cables, Temperature sensors (PT/NI/CU, NTC, Thermocouples…), Analog signal values, Joule effect, Fault current of strings, Risk assessment of overvoltages with atmospheric origin.
Electronic calculations:
Resistor / Inductor color code, Fuses, Sum resistors / capacitors, Resonant frequency, Voltage divider, Current divider, Zener diode as voltage stabiliser, Resistance to reduce voltage, Resistance for led, Battery life, Primary/Secondary winding of transformer, Antenna length, CCTV Harddrive/Bandwidth calculator.
Calculations concerning the motor:
Efficiency, Motor from three-phase to single-phase, Capacitor start motor single-phase, Motor speed, Motor slip, Maximum torque, Full-load current, Diagrams of the three-phase motor, Insulation class, Motor connections, Motor terminals marking.
Conversions:
Δ-Y, Power, AWG/mm²/SWG table, Imperial / metric conductor size comparison, Section, Length, Voltage (Amplitude), sin/cos/tan/φ, Energy, Temperature, Pressure, Ah/kWh, VAr/µF, Gauss/Tesla, RPM-rad/s-m/s, Frequency / Angular velocity, Torque, Byte, Angle.

Electrical Calculations users say on Google Play
Can I transfer my premium account from old Google account to new Google account???
The minimum short circuit current is calculated incorrectly! Especially 3 phases + neutral. 2 cables are the same as one. And what is surprising is that if you choose 1 phase, the value is completely different.
Which features is more need to use, those are locked. Builder Always demand purchases.
to many adds
Pop up ads that cover the screen and aren't even in my language, so I don't know how to get rid of them.
