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.

Digi-Key, in collaboration with Ametherm, presents a PTM describing transformer protection from inrush current using the NTC thermistor. This will provide a problem statement describing the inrush ...

Often we try to find solutions to common power magnetics issues in engineering manuals. In the process, we encounter conflicting theories among publications with no definitive solutions offered. This ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

However much care is taken, it is very difficult to keep all traces of transformer-induced hum out of the signal circuitry. It is highly irritating to find that despite the cunning use of low-noise ...
