According to the company, the large and heavy vacuum tube-based traveling wave tube amplifiers cannot be effectively replaced by GaAs transistors because they a much lower breakdown voltage.
根据公司的消息,真空管将不会被砷化镓晶体管取代。
The reflection and refraction of traveling wave are quite complicated at the sheath-crossing point of high voltage power cable, due to its remarkably noncontinuous surge impedance.
高压电缆的金属护套交叉互联导致行波在多个波阻抗不连续点产生了复杂的折反射行为,这对高压电缆线路的行波故障测距产生很大的影响。
In traveling-wave fault locating, the traditional data acquisition system can not record the fast-changed traveling waves of voltage and current for accurate fault locating.
在行波故障测距中,传统的数据采集系统无法适应采集高速变化的暂态电压、电流行波的要求,难以实现故障的精确定位。
