The reasons for the deterioration of the electromagnetic environment in the workshop distribution network of a metallurgical enterprise with powerful valve regulators are considered. A local solution to the problem of improving electromagnetic compatibility is proposed by using a digital microcontroller control system for thyristor regulators of resistance mixers. The effect is achieved due to a more accurate fulfillment of the conditions for switching the gates of each phase at the moment of zero crossing. This allows not only to reduce the level of higher harmonics of the current in the distribution network and improve the symmetry of voltages, but also to increase the stability of the equipment.
