A new class of high-power, three-phase AC-DC units with flexible outputs and industrial temp resilience aims to streamline power design in test, fab and manufacturing systems.

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.

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 ...
