UFault = 2.0 × set Start value
33 Start value = 1.0 × Un, Voltage before fault = 0.9 × Un, fn = 50 Hz, overvoltage in one phase-to-phase with nominal frequency injected from random phase angle, results based on
statistical distribution of 1000 measurements

35 Maximum Start value = 1.20 × Un, Start value multiples in range of 1.10...2.00
36 Start value = 1.0 × Un, positive-sequence voltage before fault = 1.1 × Un, fn = 50 Hz, positive sequence undervoltage with nominal frequency injected from random phase angle, results
based on statistical distribution of 1000 measurements
37 Includes the delay of the signal output contact
38 Negative-sequence voltage before fault = 0.0 × Un, fn = 50 Hz, negative-sequence overvoltage with nominal frequency injected from random phase angle, results based on statistical
distribution of 1000 measurements
