METHOD FOR CONTROLLING RESISTANCE VALUE OF WATER RHEOSTAT TYPE NEUTRAL GROUNDING RESISTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling a resistance value of a water rheostat type neutral grounding resistor, which can control the resistance value in a charged state without the need for separation from a transmission grid, has no constraint for a measurement time, and can easily carry out the control even on site.;SOLUTION: In the resistance value controlling method which controls a resistance quality of the water rheostat type neutral grounding resistor in its charged state, the electric conductivity of an internal solution taken from the above-mentioned resistor is measured in order to carry out the control by applying voltage or current across a pair of electrodes made of titanium, a titanium alloy, carbon or the like which are immersed in the solution.;COPYRIGHT: (C)2006,JPO&NCIPI
