Electric Circuits Simulator vs Matrix Calculator

The virtual laboratory stand «Relay-Contactor Circuits for Electric Drive Control» is intended for simulation training in the principles of constructing relay-contactor control circuits for a three-phase asynchronous electric drive using standard electrical components – circuit breakers, contactors, relays, push-button posts, etc. Main functions of the software product: - Construction and editing of a schematic diagram of an electrical circuit; - Construction and editing of a simulation model of a laboratory stand; - Software simulation of an assembled electrical circuit with the ability to interactively change the state of devices; - Simulated measurement of voltage in a circuit using a virtual multimeter; - Working with user project files; - Interaction with a physical relay board to implement software control of the electric drive (optional). The graphics component of the software uses the OpenGL 2.0 component base.
