Key:
a) The measuring uncertainties specified here for fault loop impedance, line imped-
ance and short-circuit current are only valid if line voltage is stable during measure-
ment and if no other electrical circuits parallel to the measured circuit are in use.
c) rdg. means reading, i.e. measured value, D = digits (i.e. number of the decimal
place with the least significance)
