METHOD AND APPARATUS FOR CONTROLLING THE AMOUNT OF MAGNETIC FLUX IMPARTED TO A FERRIMAGNETIC LOAD

摘要

a method implemented by the device and used to attack a ferromagnetic (10), such as a du00e9caleur phase in a network, makes it possible to measure accurately the amount of magnetic flux applied to the load (10) for detecting the voltage applied for a coil and by integration of the voltage detected at the time.the integrated voltage over time is proportional to the magnetic flux applied to the load (10) and is continuously compared to a preprogrammed value stored in a memory (18).when the detected voltage reaches the value pre programmed, it is disconnected from the load (10) such that a measured quantity of magnetic flux is proportional to the value of pre programmed, remains in the load (10). it is returned to the initial state distribution of a current in one direction through the coil until it is saturated.the load (10) is set with a measured quantity of magnetic flux distribution of a current in the opposite direction through the coil.a detection circuit detects the power (68) at the place where the load (10) becomes saturated during the reset cycle and detects the current flow through the coil during the cycle of adjustment, thereby preventing an overload current.
