In engineering application such case as multiple capacitor banks are included and neutral point is shared in a set of capacitor installation.The unbalanced fault condition of such capacitor installation is analyzed by the example of open delta voltage protection device
corresponding calculation model is set up and calculation method on the unbalanced voltage protection is given.The comparisons are made between such capacitor banks and other ones having the same grouping form but switched by independent switches
which provide suggestions for the project implementation in the future.
