<P>PROBLEM TO BE SOLVED: To obtain a voltage divider in which, even when an ambient temperature is changed during use, measurement accuracy of high voltage does not deteriorate and it is unnecessary to correct a scale factor. <P>SOLUTION: A temperature of an insulating oil in a first circuit constituent element chamber 1 is measured by temperature sensors 3a and 3b. A temperature of an insulating oil in a second circuit constituent element chamber 2 is measured by a temperature sensor 4. Detected values of the temperature sensors 3a, 3b, and 4 are sent to a temperature control device 8. The temperature control device 8 controls the temperature of the insulating oil in the first circuit constituent element chamber 1 on the basis of the detected values of the temperature sensors 3a and 3b. Similarly, the temperature control device 8 controls the temperature of the insulating oil in the second circuit constituent element chamber 2 on the basis of the detected value of the temperature sensor 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
