Annex A (informative) - Calculation of TRV parameters
as a function of rated maximum voltage (U[r]) and
transformer-limited fault (TLF) test breaking current
for circuit breakers of rated voltages higher than 1 kV
Annex B (informative) - Transformer-fed fault current ranges
collected through survey based on transformer size,
transformer impedance, circuit breaker rated voltage,
and rated current
Annex C (informative) - Bibliography
Specifies a supplement to IEEE Std C37.06 for high-voltage circuit breaker applications where the transient recovery voltage (TRV) peak is higher and/or its rise to the crest value occurs more rapidly than those specified in IEEE Std C37.06.
