More safety for humans,plants and assets
The number of electrical consumers in residential homes andcommercial buildings has increased dramatically in recentdecades.
Modern appliances often have quite different characteristics interms of current consumption than earlier equipment due, forexample, to the use of frequency converters in washing machines, orswitched-mode power supply units in TVs, PCs or LED lights.
There are also decentralized power generators like photovoltaicsystems or charging devices for electric vehicles.
