成果简介	NOVELTY - The stand has a control and recording unit for parameters of voltage and current, temperature and humidity of the environment with a microcontroller with a non-volatile memory (1) to which digital sensors e.g. temperature sensor (2), for measuring temperature and humidity are connected. A power supply control relay (6) is connected to a magnetic starter (7), and is connected in series with a power section protection device of the installation for switching on and off a regulated source of alternating current (AC). A terminal is connected through a bus connecting three metal containers (10) made of conductive material, and placed in a housing made of dielectric material and insulated from each other by fire-resistant dielectric material. Another terminal of the AC source is fixed to a vertical stand made of dielectric material and is an aluminum conductor without insulation. USE - Experimental stand for studying an influence of a magnitude of a single-phase earth fault current in an overhead power transmission line and duration of existence of the fault on the ignition of flammable material located in an area of the fault in electrical engineering. ADVANTAGE - The control and parameter registration unit with the microcontroller with the non-volatile memory allows tracking changes in parameters with a given time step and controlling the power supply of the installation depending on the change in parameters. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of an installation for studying an influence of various quantities characterizing a short circuit of a wire to ground on possibility of ignition of combustible material.(Drawing includes non-English language text). 1Non-volatile memory 2Temperature sensor 6Power supply control relay 7Magnetic starter 10Metal containers
