R&D engineers have traditionally found it a challenge to measure dc inrush current and current during dc voltage transients because these measurements require complex setups with multiple pieces of ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

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 ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

Matt Cuhadar is a key member of the Ametherm team, Matt Cuhadar has provided support for the company's customers as an application and sales engineer for the last two years. He holds a B.Sc. in ...

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 – ...

A quasi-dynamic thermal model accurately predicts inrush-induced heating in MOSFETs, while also accommodating different circuit topologies. David Divins, Senior Field Applications Engineer, ...
