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 ...

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.

A simple approach based on original research attacks inrush currents at the source - the power transformer. The use of special core materials and transformer design/construction techniques overcomes ...

Most petrochemical industrial facilities have numerous small (30kVA or 45kVA) transformers spread throughout the process units serving lighting and power distribution panelboards. In the U.S., the ...

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 ...

TDK-EPC has extended its range of EPCOS inrush current limiters (ICL). The P11 series (B57211P*) covers a resistance range from 4 to 25 ohms (R25). TDK-EPC has extended its range of EPCOS inrush ...

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – ...

CARSON CITY, NV--(Marketwired - Oct 8, 2013) - Ametherm today announced that it has acquired the SURGE-GARD™ inrush current limiter product line, formerly manufactured by RTI Electronics, from ...
