Each element of the high voltage distribution network is at risk of a series of defects that can result in energy losses and/or a major security risk.
One of the most frequent failures in the distribution network is the overheating of individual components due to transition resistance. Transition resistance occurs in imperfect places (damaged, outdated or unprofessionally installed) electric joints. Due to the increase in series resistance,
there are energy losses in the form of what is known as heat loss. It is not only an economic problem but also a security problem – due to the further worsening of parameters, the temperature of the
damaged joint can increase its temperature until a fire breaks out that may be highly destructive due to the high voltage.
