荷兰发电委员会（NV SEP）正在计划扩建荷兰380千伏电网。由于路权有限，新的架空高压线路将与新塔上现有的高压线路相结合。然而，这将增加系统间故障的风险。为了避免过度损坏和不可接受的长停机时间，作者描述了如何适应现有的保护概念来正确处理系统间故障。
The Dutch Electricity Generating Board (NV SEP) is planning an extension of the Dutch 380 kV network. As a result of the limited number of right of way the new overhead high voltage lines will be combined with existing high voltage circuits on new towers. However this will increase the risk of intersystem faults. The authors describe how, in order to avoid excessive damage and unacceptable long outage times the present protection concept will be adapted to handle inter-system faults correctly.
