Abstract
A method of calibrating a recloser voltage measurement system. In one example, the recloser voltage measurement system includes a voltage divider and a voltage adjustment circuit. The voltage divider is electrically coupled to a recloser. The voltage adjustment circuit is electrically coupled to an output of the voltage divider. The method includes determining a first voltage measurement at a high voltage input to the recloser. The method also includes determining a second voltage measurement at an output of the voltage adjustment circuit. The method further includes calculating a difference between the first voltage measurement and the second voltage measurement. The method also includes determining a target voltage gain based on the determined difference between the first voltage measurement and the second voltage measurement. The method further includes adjusting a voltage ratio of the voltage divider by setting the voltage adjustment circuit to the target voltage gain.
