Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system, particularly sags that trip loads.

When motors start across the line, they typically draw five times the running current. This temporary “inrush” is an overload condition. To handle inrush while still providing adequate overcurrent ...

Sometimes the hardest part is getting started. Choose the best motor starting method for a particular application by keeping a few guidelines in mind. For example, while across-the-line starting is ...

A series of three-phase induction motor softstarters prevents motors from experiencing the stress of high inrush currents (typically six to nine times nominal values) that can cause electrical and ...

Compressor hard-start devices are a luxury item for service technicians to use in rectifying a myriad of compressor start problems. It is true that the majority of hard-start device applications ...

Due to the wide variety characteristics of the induction motor, it plays the premier role in the industrial sector. Some of those are self starting, rugged construction, high efficiency, good power ...

Brushless dc motors have the advantages of high reliability and smaller size, but the absence of brushes can pose challenges. One challenge is the requirement for electronic commutation and control, ...

(MENAFN- GetNews) When the centrifugal pump is started, there is no water in the outlet pipeline of the pump, so there is no pipeline resistance and lifting height resistance. After the centrifugal ...
