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 ...

A transformer switching onto a line can sometimes cause a circuit breaker to trip or a fuse to blow. This phenomenon occurs even if the transformer presents no load, such as when the secondary is open ...

CARSON CITY, NV--(Marketwired - Sep 28, 2016) - Ametherm today introduced a new series of inrush current limiting NTC thermistors designed to withstand high input energy from 500 J to 900 J and steady ...

CARSON CITY, NV--(Marketwired - Jul 24, 2013) - Ametherm today introduced a new series of inrush current limiting NTC thermistors designed to withstand high steady-state currents from 6 A to 50 A and ...

The development of new generations of transformers and line reactors is radically simplified and accelerated by a powerful new automated software toolbox from the Vector Fields Software product line ...

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