IEC_60599_TYPICAL_RATES_OF_GAS_INCREASE

Formula​

=IEC_60599_TYPICAL_RATES_OF_GAS_INCREASE(dga, hasCommunicatingOltc?)

Description​

Checks whether the values of the DGA are over the typical rate of gas increase values for the 90% of the samples.

Refer to IEC 60599:2022, Section 8.3 - Rates of gas increase, page 21.

If the 'hasCommunicatingOltc' parameter is not entered the value defaults to false.

Output​

The outcome of the application of this rule.
