Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...

Over the years, engineers have developed many definitions for measuring power with distorted voltages and currents. However, none of these definitions successfully characterize all of the ...

Howdy guys - I have an XPA-2 amp hooked up to a pair of B&W683's and am curious how many watts (in real time) I am using. I am not worried about over driving the speakers or worried that the amp is ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

The instrument works on the principle of a combined bridge-vector-meter and it is capable of analyzing capacitive and inductive loads. HAEFELY HIPOTRONICS has launched the new high precision tan δ/ ...

Standby power refers to the electric power consumed by electronic appliances while they are switched off or in a standby mode – but still connected and still drawing power. Fundamentally, standby ...

Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, inefficient lighting, equipment that is always left on when ...

Your utility Power Factor is the ratio of the system’s Real Power and the Apparent Power (Eq. 1, Fig. 1). This unitless factor ranges from −1 to 1. The Power Factor ratio aptly describes the type of ...
