Abstract
This chapter describes various types of cable testing, such as insulation resistance test, rectified current surge test, power frequency surge test. The definition of the active resistance of conductors and the electrical performance of the conductors is given. Diagnostics and monitoring of power cable lines are described in detail. All stages of the creation and operation of high-voltage cable lines (CL)—cable production, route selection for laying, laying, diagnostics, repair and replacement are quite labour-consuming and expensive. The reasons for this should be mentioned as: (a) high quality requirements for electrical insulation, sealing and protection against mechanical damage, (b) large extent, (c) deep in the ground, (d) significant probability of mechanical damage in case of uncoordinated extraneous earthworks within the track. All of the above applies to the cable lines of marine laying. (Only their mechanical damage is of a different nature—mainly trawling).
