So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

While troubleshooting the cause of a motor failure, you discovered a phase imbalance of 5% at the motor leads. Now what? You need to find and fix the cause, but where do you start? Begin by ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Origo introduced a phase identification system that can be used to phase all primary, secondary and three-phase circuits by proximity. Nov. 18, 2019 Origo has just introduced the new 4th generation G4 ...

The loop output can go directly to an ADC (analog-to-digital converter) or DMM in the configuration of K22 shown. If, however, filtering is needed to reduce noise during measurements, K22 can be ...

This whitepaper compares single phase and three phase circuits from the component count, stress level and complexity standpoints. The document shows that on most cases, single phase circuits are the ...
