Dr Tony's Free Electrical Calculator

An application for electrical engineers to undertake useful calculations.

This is a FREE android application for aiding electrical engineers to quickly perform essential calculations for their design or inspection tasks. A number of equations were selected from Dr Tony Sung's authored textbook "Advanced Electrical Services Engineering" into the application to aid electrical designers, installers and inspectors to quickly calculate the result from the app. It consists of a number of Earthing, High Voltage and Low Voltage equations that are commonly used by electrical engineers needing to work with relevant BS EN and BS standards such as BS EN 50522, BS7430 and BS7671.

This is a beta version. Please email us if you come across any error using the feedback page at start-up of the app. Thank you.

A more advanced premium version has been planned for a future release. Please check back after January 2018.
