Abstract
PURPOSE: To facilitate an easy measurement of the simulation input, by installing a current transformer which generates the current to cancel the current supplied from the 2nd current source in case the current of the 1st current source is supplied to the load.
CONSTITUTION: The current transformer 7 has the windings 7aW7c of the same number of coils. One end of the winding 7a reaches the other end via the current transformer 2, contact 8 and winding 7c respectively. The winding 7b is connected to the current source 4 via the contact 3. The contact 9 is connected between the both ends of the winding (c) and then to the load 5 via the contact 8. The contacts 3 and 8 are usually opened, and thus the current of the current transformer 2 flows to the load 5. But the current of the source 4 which is the simulation input does not flow to the load 5. When the contacts 3 and 8 are closed, and the contact 9 is opened, the current of the source 4 flows to the winding 7b. At the same time, the current of the transformer 2 and the current supplied from the winding 7c cancel each other. And only the current of the current source 4 flows to the load 5. As a result, the measurement can be facilitated for the simulation input.
