How can we detect internal compression defects in elbow-type cable joints of ring-main units (RMUs) in advance by monitoring the temperature difference of the outer sheath of the cable joints?
In the daily operation and maintenance of power distribution systems, cable accessories are often the most frequently faulty parts, especially the elbow-type cable joints in ring-main units (RMUs). If the compression process is not standardized, the internal contact resistance will increase, and ...
