IEC 61238, section 6.3.4demands short-circuittests where current levelshould raise theconnector temperaturebetween 250 °C and270 °C
IEC 61238 connectors testing system
What’s IEC 61238?
IEC 61238 is theinternational standardabout connectors forpower cables for ratedvoltages up to 30 kV
Depending on theconnector’s section thecurrent needed to raisethe temperature couldbe higher than 25 kA
