This paper describes the implementation of an app for calculating low frequency electric fields outside electrical installations. The app is based on a 2D parametric geometry chosen in such a way that it approximates a large class of electrical installations, which consist of a tower or platform surrounded by one or two fences. The accuracy of the 2D geometry is verified against a sample 3D geometry and is shown to be sufficient for production design. The app is expected to be very handy during the design of electrical installations and significantly reduces the risk of late design changes.
