1. The basic function of current transformersThe current transformers can convert primary currents with larger values to secondary currents with lower values through a certain transformation ratio, which are used for protection and measurement purposes. For example, a current transformer with a transformation ratio of 400/5 can convert the actual 400A current to 5A current.2.…
DetailsBrief 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…

DetailsThe 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…
DetailsCurrent-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…
