Out-of-step protection is a critical component of modern power system protection schemes—its importance has grown ...

Many voltage regulators are of the fixed output variety and include the voltage divider internal to the regulator. There are definite advantages to this approach, which allows active voltage trimming ...

Classic techniques like videofluoroscopy, stationary manometry, and ambulatory 24 h pH-metry are routinely used in the clinic to study patients with dysphagia, chest pain and reflux-related symptoms.

The global issue of antimicrobial resistance has been called a “slow motion catastrophe” resulting from the excessive and often inappropriate use of antibiotics to fight bacterial infections. 1 A long ...

Keysight Technologies today introduced three low-frequency options for its E4982A LCR meter. With these new options, the E4982A is suited for RF inductor, coil, and EMI filter manufacturers that are ...

Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...

We’ll begin by covering some of the basic mathematical relationships that everyone learns in electrical trade (or engineering) school. Unfortunately, many people seem to forget these basics in the ...

With the increasing dependency of back up systems on batteries and the escalating cost of replacing batteries, instrumentation and software systems that can measure, trend and manage the lifecycle of ...
