Brief description Principle The main characteristics of RCD are shown in the below picture. Its iron core surrounds all current-carrying conductors of an electrical circuit, and the magnetic flux generated in the magnetic core is related to the arithmetic and current of these conductor currents in an instant; the current flowing in one direction is…

The Critical Impact of Open Circuit Conditions in Current Transformers Current transformers (CTs) are indispensable in the measurement and monitoring of electrical currents in various applications. Understanding the impact of open circuit conditions on these devices is crucial for maintaining safety and reliability in electrical systems. How Current Transformers Operate A current transformer typically features…
Current-type signals, the external characteristics of the ideal situation, is equivalent to a very large voltage source in series with a very large internal resistance. In this way, when the load impedance is much smaller than its internal resistance, the current is always equal to its “short circuit current”. Its main advantages are: as long…
Before talking about accuracy and linearity, let us talk about the concepts of several errors: 1. Absolute error: the difference between the measured value and the ideal value; 2. Relative error: the ratio of the absolute error of the measured point to the ideal value of the measured point; 3. Reference error: the ratio of…
