The long-term behaviour of bolted joints used in high current systems is influenced by different ageing mechanisms. One of these mechanisms is the degradation of the joint force depending on temperature and time. If the joint force falls below a critical value, the joint resistance, the thermal dissipation and thereby the temperature of the joint can increase to a critical level. According to IEC...
