用于直流传输的高压电缆要承受一系列的工作条件。电缆内部电场的分布高度依赖于电缆的负载和极性反转等。这是因为绝缘体的电导率取决于温度和电场。确定内部电场过程中的一个重要参数是空间电荷。为了彻底了解电缆的行为，了解不同工作条件下空间电荷的位置和数量至关重要。
High voltage cables that are used for DC transmission are subjected to a range of operating conditions. The resulting distribution of the electric field inside the cable is highly dependent on, for instance loading of the cable and polarity reversals. This is because the conductivity of the insulation is dependent both on the temperature and on the electric field. An essential parameter in the process to determine the internal electric field is space charge. For a thorough understanding of the behavior of the cable, knowledge of the location and amount of space charge under different operating conditions is paramount.
