| Abstract: | A new weak DC sensor which is used in measurement of lightning current is introduced. The sensor using a magnetic multivibrator is composed of MOSFETS and is made of new Fe-based supermicrocrystalline soft magnetic alloy. It has a very simple construction with small valume, high sensitivity, high linerity, low power losses and no contact. Its principle is analyzed and some experimental results are shown. |
| Keywords: | Lightning current Current sensor Circuit of magnetic multivibrator Sensitivity Linerity |
