Improper voltage is the one of the greatest causes of failed compressors in three-phase units. We are allowed a 10% deviation over or under the unit nameplate-rated voltage. Most technicians know to ...

A voltage divider is a passive linear circuit used to create a voltage less than or equal to the input voltage. It is a conversion device composed of a high-voltage arm and a low-voltage arm. The ...

A steady supply of voltage is important in industrial and commercial applications to maintain equipment performance, product quality, and safety, while also minimizing downtime. Voltage sags (where ...

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 ...
