For dynamic current measurement (protection purposes) the ABB sensors KECA 80 C184, and
KECA 80 C216, fulfil requirements of protection class 5P up to an impressive value reaching
the rated short-time thermal current I
sensors, measuring class 0.5 is reached for continuous current measurement in the extended
accuracy range from 5 % of the rated primary current I
common for conventional current transformers), but even up to the rated continuous thermal
current I (1 250 A or 3 150 A). That provides the possibility to designate the corresponding
cth
accuracy class as 5P400, proving excellent linearity and accuracy measurements.
