Tolerances are based on the preset matching parameters. Higher tolerances are to be expected for calculated
values dependent on the matching factors for currents and voltages.
Measured values of differ-
ential protection
Measured values of restrict-
ed earth fault protection
Tolerances are based on the preset matching parameters for a protected object with 2 sides and 1 measuring lo-
cation on each side. Higher tolerances are to be expected for calculated values dependent on the matching factors
for currents and the number of measuring locations.
