大量的试验已经令人信服地证明了换向原理的有效性，即用真空灭弧室作为在高压下中断大直流电流的手段。20 kV时超过15 kA的电流已被感应电路中的单个设备中断。测试报告中，较高的电流被清除并联断续器。断路器已经进行了串联测试，表明该原理可以扩展到高压。描述了一种专门为这种类型的断路器设计的高速机构。生产高压直流断路器的必要技术似乎已经掌握。
The effectiveness of the commutation principle, using vacuum interrupters as a means for interrupting high direct current at high voltage, has been demonstrated convincingly by a large number of tests. Currents in excess of 15 kA at 20 kV have been interrupted by a single device in an inductive circuit. Tests are reported in which higher current were cleared by paralleling interrupters. Interrupters have been tested in series, indicating that the principle can be extended to high voltages. A high speed mechanism is described which was designed specifically for circuit breakers of this type. The necessary technology for producing HVDC circuit breakers appears to be at hand.
