3. System description 3.1 Features 3.1.1 Areas of application Installations featuring high-resistance neutral-earthing are used whenever power supply fail- ure would incur significant costs due to production downtimes (e.g. the automotive industry, chemicals industry). With this type of installation, an insulation fault between a phase and the earth will not result in failure of the power supply. -
