<p>PURPOSE:To obtain the title transformer device with which a large load can be taken out from a bushing by a method wherein a voltage terminal, with which the voltage formed by the capacitance ratio of the main electrostatic capacitance and the tap capacitance formed by a capacitor electrode, and load are connected using an oil duct. CONSTITUTION:A voltage terminal, with which the voltage modified by the capacitance ratio of the main electrostatic capacitance 3a and the tap capacitance 3b formed by a plurality of sheets of capacitor electrode 4 provided on the circumference of the center conductor 2a of a capacitor bushing, and load 11 are connected by an oil duct 12. For example, one end of the oil duct 12 is connected to the above- mentioned voltage terminal 6, and the load 11 of a measuring instrument or a controller and the like is connected to the other end of the oil duct 12 through the intermediary of an amplifier 14. Consequently, as the electrostatic capacitance other than the bushing, namely, the electrostatic capacitance which is generated by the power cable and the adjustment capacitor heretofore in use can be eliminated, the voltage of the voltage terminal does not drop, high and accurate voltage can be obtained. Also, as a power cable is unnecessitated, a complicated terminal processing work to be performed on a cable is also unnecessitated.</p> |
