AC Current transformer for higher frequencies
Differential current transformers are used for measuring the OFFSET current on single-or three-phase supply cables referred to go-and-return line. The monitoring of the leakage currents to earth is also provided. With its high-permeable material, the current transformer will safely recognize the OFFSET current. Currents of 10 mA off will already be recognized. The large hole enables direct feed-through of a wide range of supply cables.
