Space traveling wave tube (TWT) is one kind of microwave vacuum tube for communication, which must have high reliability, high power. The life of the space TWT is requested for a long lifetime of 10–15 years. In order to shorten the testing process, accelerated aging tests are performed at higher than normal operating temperature and currents of cathode. But in the process of the actual test, the...

UHV long transmission line takes on distinct characteristics of distributed parameters, and it has great capacitive currents. Traditional phase segregated current differential protection is severely influenced by distributed capacitive current. In order to realize differential protection with high sensitivity and reliability for UHV transmission line, phase segregated current differential protection...
