Power quality in relation to the requirements of electromagnetic compatibility

In modern systems, where many equipment are controlled by electronic devices, power transmission and distribution networks are increasingly turning into “smart grids”. There is the question of the immunity of these equipment to the action of electromagnetic fields generated by other equipment, as well as the immunity of other control and monitoring devices to the action of electromagnetic fields generated by electrical installations. Transmission and distribution networks, due to their size, are one of the most important sources of disruptive electromagnetic fields. But due to their increased complexity and dependence on embedded technologies, new networks in turn can become “victims” of disruptive electromagnetic fields, which can adversely affect the reliability of the power supply.
