The voltage drop across these diodes (less than 1 V for Si diodes) may completely be neglected when high voltages are to be measured. The measuring instrument may be included in one of the two branches. In either case it reads a magnitude of charge per cycle, or the mean value of the...
Drop-out fuse cutout and load switching fuse cutout are outdoor high voltage protective device.To be connect incoming feeder of distribution transformer or distribution lines ,it mainly protects transformer or lines from short circuit and overload,and on/off loadi...
The proposed method successfully detects the faulted transmission line, fault type, and the distance to the fault. Besides, it makes use of phasor measurement unit data and it is non-iterative. The grid is split in a user-determined number of subareas based on the phasor mesurement unit ...
