摘要

对电缆终端周围的电场进行了直流场测量。研究了外加电压后沿表面的磁场变化及其时间发展。在施加电压后的短时间内，测量结果与模拟结果的一致性比较好。经过较长时间后，与模拟结果出现偏差。讨论了造成这种差异的可能原因。

DC field distribution around an HVDC cable termination

DC field measurements of the electric field around a cable termination have been performed. The field variation along the surface as well as its time development after voltage application is studied. The agreement between measured and simulated results is relatively good, for short times after voltage application. After longer time, deviations from the simulated results occur. Possible reasons for this discrepancy are discussed.
