In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

The Cordless Digital Phasing Tester allows linemen to test for phase sequence and angles, voltage ranges between 4 kV and 69 kV and operates at a range of up to 100 ft.

Measuring phase noise with a spectrum analyzer. The primary advantage of dedicated phase-noise analyzers. The cross-correlation method. Using a spectrum analyzer is the oldest, most straightforward, ...

Hi-Line Utility Supply Co. has enabled linemen to remove one more obstacle to their safe return after working on high-voltage lines in the field: the cord currently strung between most phase testers ...
