How is current measured

WebThere are different measurement classes of current transducers which describe the accuracy and the phase shift of the transducers. The classes range from 0,1 to 5. Class 0,1 means that the accuracy of the measured amplitude is 0,1 % and the phase shift is ±5 minutes. In class 5 the accuracy is 5% and the phase shift ±120 minutes. WebHow to measure current. Current can be measured using a device called an ammeter. Ammeters should always be connected in series with the part of the circuit where you wish to measure the current, as shown in the figure below. This is because current has to flow through the ammeter in order for it to read the value.
