Abstract :
The space charge that accumulates in DC cables can, mathematically, be resolved into two components. One is related to the temperature and the other to the magnitude of the electric field strength. Analytical expressions for the electric fields arising from each of these space charge components are derived. Thereafter, the significance of these field components under both normal operating conditions and immediately following polarity reversal is discussed
