PMI’s line of power quality monitors can be used with Canvass to quickly and easily locate voltage unbalance problems.

 

Voltages are rarely perfectly balanced in three-phase systems.

 

Although small unbalances are not usually a problem, if this unbalance becomes too great then the unbalance can cause problems especially for three-phase motors or compressors.

 

Fortunately unbalance is easy to measure with PMI three-phase Boomerangs and Revolutions with Canvass.

 

Canvass provides the tools to help identify and locate the source of voltage unbalance problems.

 

Voltage unbalance in a three-phase system can be defined as the max deviation from the 3-phase average divided by the average.

 

Voltage unbalance is usually caused by single-phase and non-linear loads that are not evenly distributed.

 

Sources of voltage unbalance are usually found inside of facilities...
