Partial discharge. VIII. PD testing of solid dielectric cable

For pt.VII see ibid., vol.7, no.4, p.9 (1991). The development of solid dielectric cable is discussed and its potential defects are described. Limitations to partial discharge (PD) measurement and testing are discussed, and its use for detecting cavities (also referred to as voids), which are probably the most common defect in solid dielectric cable and the primary defect detected by PD test, is discussed. PD test standards for solid dielectric cable are reviewed. Practical aspects of PD testing are addressed. Alternative, nonelectrical test methods are briefly described and assessed.<>
