چکیده انگلیسی
This paper presents experimental results from surge and energization field tests carried out on a 225Â kV underground XLPE cable with 64Â km and 17 major sections with cross-bonding of sheaths. The surge tests applied a 2Â kV surge to minor and major sections having 1080Â m and 3952Â m, respectively. The tests on the minor section were intended to excite different propagation modes and observe the respective cable responses. In the energization tests, the transient current and voltage at the sending end were measured, when energizing the full cable, from each end. Measured results of current show the impact of transformers in the network and the reactive compensator. The energization tests were simulated in EMTP using detailed and simplified cable models, corresponding to using a separate model for each cable minor section or a homogeneous equivalent for the whole cable length. Computed results show that using the simplified model does not reduce the accuracy of simulations of core voltages and currents, because the simulated test concerned only core conductor quantities.
