This month in EC&M's forum for your power quality questions, Mark McGranaghan, vice president of consulting services, teams up with several other experts from EPRI-PEAC to address the topics of ...

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 ...

Abstract: This paper presents a comparative study of transformer inrush current and fault current. As the transformer is one of the key component in power system network so stability, security and ...

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.

Abstract: Transformer magnetizing inrush current represents a typical electromagnetic transient phenomenon in power systems, frequently occurring during transformer energization or upon voltage ...

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 ...

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 ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...
