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 ...

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 ...

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 – ...

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.

Remember fundamentals and practice situational awareness in taking measurements. It’s not only using the right probe, but it’s also using the probe right. Eliminating measurement artifacts is tricky, ...

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 ...
