Partial discharges in low-voltage cables [PDF]
IEEE International Symposium on Electrical Insulation, 2002 A novel method, utilizing partial discharges, is presented which has the potential for locating breaches in the insulation of in situ, low-voltage, multiconductor cables. The measurement technique is intended for use in situ on 600-V-class nuclear power plant cables, and so representative cable types were used in the experiments described: shielded ...

Online Estimation of Cable Harmonic Impedance in Low-Voltage Distribution Systems [PDF]
IEEE Transactions on Instrumentation and Measurement, 2020 Incorrect values of cable harmonic impedance can lead to wrong conclusions when assessing impact of current distortion on the power network. A theoretical derivation of resistance and reactance for harmonic frequencies is not sufficient as it neglects operating conditions of cables as well as their configuration and actual installation pattern. In this

Investigation on Ampacity for Direct Burial Low-Voltage Power Cables [PDF]
International Journal of Innovative Solutions in EngineeringGenerally, cable ampacity is the physically allowable continuous current that a cable can carry under real installation conditions. Allowable continuous current is the current in a conductor limited by the temperature rise in the insulation.
