In this chapter, field test results on various three-phase cables are explained, and a comparison with simulation results is carried out. Surge characteristics and the effect of various parameters are investigated based on the field test and simulation results. Also, electromagnetic transients program (EMTP) simulation results by various cable models prepared in the EMTP are discussed.
6.1 Cross-bonded Cable
6.1.1 Field Test on an 110 kV Oil-filled (OF) Cable
Figure 6.1 illustrates a field test circuit on an 110 kV OF cable with a core cross section of 610 mm2 and Al sheath [1].
Figure 6.1 A field test circuit of an 110 kV OF cable: (a) field test circuit; (b) cross section of 110 kV OF cable; and (c) cable arrangement
An impulse voltage 7.3 kV with wavefront duration and wave tail is applied to the middle-phase core at the sending end. Figure 6.2 shows measured results and Figure 6.3 gives the simulation results [2, 3] by a frequency-domain transient analysis program (FTP) [2, 4]. A satisfactory agreement is observed in the ...

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
