Title: Instrument transformer for measuring current having magnetic-field sensor
Inventor: TOOMASU ZAITSU
IPC: G01R15/18
Filed: 1992-07-01
Abstract: PURPOSE: To provide a potential transformer which enables a current to be measured transmitted to a magnetic flux density in an air gap with a sufficient accuracy and linearly. CONSTITUTION: A magnetic circuit which comprises a C-shaped magnetic core 1 having an air gap 2 is excited by an electrically conductive body 8 through which a current (i) to be measured flows through. A magnetic sensor 5 is arranged in the air gap 2. An output of the magnetic sensor 5 is proportional to the current (i) to be measured. When the magnetic core is axially projected on a projection surface which is perpendicular to a projection axis, two profiles are formed, wherein a circumferential length of an outer profile 6 is determined to be three times longer than the circumferential length of an inner profile 7. Due to such a construction, a smoothing effect which compensates for a magnetic characteristic of the nonlinear magnetic core so that the current to be measured can be transmitted to the magnetic flux density with a sufficient accuracy and linearly.
