1) AC type Current Transformer:
The AC type Current Transformer is developed and designed for the power frequency sinusoidal leakage current, and can reliably protect the sinusoidal leakage current that is suddenly applied and slowly rising.
2) Type A Current Transformer:
In addition to the reliable protection of the sinusoidal leakage signal, the A-type Current Transformer can also reliably protect the leakage signal containing the pulsating DC component.
3) Type B Current Transformer:
Type B Current Transformer can reliably protect sinusoidal AC signals, pulsating DC signals and smooth signals.
