SHIELDING METHOD FOR REDUCING EXTERNAL MAGNETIC EFFECTS IN LOW-POWER CURRENT TRANSFORMERS

摘要

The present invention relates to a shielding method for reducing the effects of external magnetic fields on low-power transformers for the purpose of a shielding that will reduce the effect of external magnetic fields on transformers in low-power current transformers regardless of the direction and density of such external magnetic fields. The main principle of the invention is that conductive rings provided to cover the device generate a magnetic field opposite to the external magnetic fields, thereby reducing the external magnetic fields' effect on the device.
