Scientists at South Ural State University have created a portable generator that measures the current passing through a person's body in the field. According to TASS, the device will refine industry electrical safety standards.
The generator outputs an adjustable sinusoidal current from 0 to 10 mA at a voltage of up to 20 V. Unlike bulky stationary analogs, the device operates in workshops and substations. It measures the threshold of perceptible current under the simultaneous action of electric and magnetic fields — such data has not been collected in Russia.
The existing GOST R 12.1.038-2024 does not consider the combined effect of fields. The new measurements will form the basis for adjusting the permissible voltage and current limits. The development is addressed to labor protection specialists who will literally rewrite safety rules. For an ordinary electrician, it's a question of whether they will get shocked or not.
