Can the isolation be measured on a digitalSTROM installation without any hesitation?
Yes, there is no connection to ground. How long may the lead (230V line) be on a dSM. 50m (total of the entire length of the lead connected to a dSM) and more. The permissible line resistance and permissible voltage drops and/or the connected load impedances are crucial. Here the general regulations for electrical installations apply, which must be complied with for all electrical installations, irrespective of digitalSTROM.
