This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Current conveyor (CC) circuits are among the most common current-mode circuits and are used as critical building blocks in a variety of complex circuits. Unlike voltage-mode circuits, current-mode ...

480 Voltage Power and Current Formula for single-phase and three-phase circuits: compute kW, amps, and power factor from 480 V line voltage using P=V*I*pf and P=sqrt(3)*V*I*pf for balanced loads ...

Instrument transformers provide accurate current and voltage measurement for protective relays, metering, and monitoring. By scaling high system values to safer levels, they enhance electrical safety, ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

Abstract: This paper explores the use of ATPDraw and Ansoft Maxwell and other simulation software on the induced current, induced voltage of the overhead ground line and the electromagnetic field ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...
