Transformer OCP Sizes

Allows you to create and modify overcurrent protection sizing options for transformers.

Opens the Transformer OCP Sizes dialog box:

Transformer OCP Sizes Dialog Box​

Voltage Section​

OCP sizing options are organized by the primary voltage of the transformer.

Each voltage can have up to one OCP sizing option. If a voltage does not have a sizing option, the OCP for the transformer will be sized the same way as other distribution equipment.

  •  Primary Voltage: ▾ Sets the current OCP sizing option. The OCP sizes listed in the OCP Size section correspond to the current voltage.

  •   Creates a new voltage.

  •   Deletes the current voltage.

  •   Renames the current voltage.

OCP Size Section​

Each row in the grid lists a transformer size for the current voltage.

  •  Transformer Size The size of the transformer in kVA.

  •  Single-Phase OCP Size The ampacity of the upstream OCP for a single-phase transformer.

    warning

    If 0 or no value is entered, the Transformer Size will not be listed as a Size ▾ in the Panel Edit command for single-phase transformers.

    The OCP for the transformer will be sized the same way as other distribution equipment.

  •  Three-Phase OCP Size The ampacity of the upstream OCP for a three-phase transformer.

    warning

    If 0 or no value is entered, the Transformer Size will not be listed as a Size ▾ in the Panel Edit command for three-phase transformers.

    The OCP for the transformer will be sized the same way as other distribution equipment.

  •   Creates a new kVA. The new kVA will be the next largest after the largest kVA in the grid and will be added to the bottom of the list with default settings.

  •   Deletes the current kVA.
