An instrument that can measure the electric current is called an ammeter. The ammeter must connect in series with the circuit whose current is to be measured. Other various instruments are also used to measure the electric current. Hall effect current sensor transducers Current transformer (CT) (...

Electric vehicles (EVs) are a promising technology to reduce emissions, but its development enormously depends on the technology used in batteries. Nowadays, batteries based on lithium-ion (Li-Ion) seems to be the most suitable for traction, especially nickel-manganese-cobalt (NMC) and nickel-cob...
Decaying DC (DDC) offset current mitigation is a vital challenge in phasor current estimation since it causes malfunctioning/maloperation of measurements and protection systems. Due to the inductive nature of electric power systems, the current during fa
Like voltage, current can bealternating current (AC)ordirect current (DC). The electrical current is the intensity or rate of flow of an electric charge. Similar to measuring the voltage, we sometimes need to measure very tiny currents, i.e., in the microamp range, while other times we ...
