Electric Field Determination in DC Polymeric Power Cable in the Presence of Space Charge [PDF]
, 2007 The pulsed electroacoustic (PEA) technique was used to perform space charge measurements in polymeric power cables. However, for a practical dc power cable the electric field is affected by conductivity of the material, which is a function of both ...

On the intrinsic thermal stability in HVDC cables [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2007 The paper deals with some important aspects of steady state thermal stability in the insulation of HVDC cables. The resistively graded electric field distribution and the temperature distribution, under steady state, in dc cables, are interrelated. The dc conductivity is known to be a function of stress as well as of temperature.
