INSTRUMENT INDUCTANCE COIL

摘要

FIELD: measurement technology. SUBSTANCE: coil 2 for electrical and magnetic field metering and display device is wound on high-permeability magnetic core 1 of toroidal shape. This multilayer winding is placed on external surface circumference of toroidal core 1. Coil 2 has thickness approaching or equal to thickness of toroidal core 1 and its length approaches or is equal to height of toroidal core 1. EFFECT: improved sensitivity and confidence of data obtained. 1 dwge
