Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

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, ...

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 ...

With power efficiency a high priority on today's electronics, measuring the effects that switching power supplies have on AC mains is critical from an interference perspective. Plus, a power supply's ...

Many applications today, including industrial machinery, power tools and other high current equipment, use limiting inrush current as a major design consideration to combat the problematic effects of ...
