earth-fault current do not exceed given values;
- ARD with assessment means, reclosing only if the prospective line current does not exceed a given value;
- ARD with assessment means, reclosing only if the prospective earth-fault current does not exceed a
given value;
- ARD that reclose without any assessment.
