A system and method for determining when an electronic interrupting device will open in response to detecting overcurrent, where the interrupting device protects a transformer in a power distribution network. The method includes obtaining a time/current through fault protection curve that is defined by a plurality of time/current points for the transformer that identifies when the transformer may experience thermal or mechanical damage in response to a certain current flow over a certain time in the transformer windings, selecting a time multiplier, and determining an operating curve for the interrupting device by multiplying the multiplier and a time portion of each of the plurality of time/current points on the through fault protection curve, where the operating curve identifies when the interrupting device will open in response to a certain current flow over a certain time.

Transformer overcurrent protection

A contact lens case is disclosed. The contact lens case has a fluid tank that stores fluid (e.g., contact lens solution, water, etc.). The contact lens case also has two lens assemblies (e.g., a first lens assembly and a second lens assembly), wherein each lens assembly has a lens reservoir that stores a contact lens. Further, each lens assembly has a pressure pump that upon actuation, draws fluid from the fluid tank, through a suction line and a one-way valve, to the corresponding lens reservoir.
