A number of measurements require an amplifier whose input terminals are galvanically isolated from its output and power terminals. Such devices, often called parametric or isolation amplifiers, are ...

Today, optocouplers are a ubiquitous electronic component, found in almost any piece of electrical equipment and in most industry segments. Since their introduction over twenty five years ago, ...

Insulated-gate bipolar transistors (IGBTs) require full protection to avoid damage and failures resulting from conditions such as short circuits, overloads and overvoltages. The protection is key to ...

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Isolation is a means of preventing current from flowing between two communicating points. Typically, isolation is used in two situations. The first is where there's the potential for current surges ...

With the right equipment and training, it’s possible to safely work on energized power lines in the 500 kV range with bare hands. Most of us, though, don’t have the right equipment or training, and ...
