The current transformer manufacturer explains in detail what the load of the current transformer refers to? Why does the accuracy decrease when the allowable value is exceeded? Answer: The load of the current transformer refers to the instrument panel, instruments and equipment connected between the secondary winding terminals. The total impedance of connected transmission lines, etc., is generally expressed in impedance values. The size of the secondary load impedance of the current transformer has a great impact on the accuracy of the voltage transformer. When the secondary load impedance of the current transformer exceeds its allowable secondary load impedance, the accuracy will decrease due to the current transformer When the secondary load impedance of the transformer exceeds the allowable secondary load impedance, the value of the self-inductance electromotive force will increase greatly and the iron core will be saturated. In this case, a large part of the primary current will be used to provide The self-induced electromotive force will increase the deviation of the voltage transformer, and the accuracy will decrease accordingly.
