IEC_60599_DETECTION_LIMITS

IEC_60599_DETECTION_LIMITS

Formula​

=IEC_60599_DETECTION_LIMITS(dga)

Description​

Checks whether the values of the DGA are below the analytical detection limits.

If they are, this formula returns the DGA with the corrected values.

Refer to IEC 60599:2022, Section 6.1 - Examination of DGA values, page 17

Output​

The sample formatted in the same way as the output of the FORMAT_DGA formula but with the minimum detection limits applied to the results.
