When you use hover with sprites it makes for a seamless transition, unlike when you load the file on the hover state, which leaves a blank space until that file is loaded.

The sensitivity of the proposed protection scheme is not impacted by the factors such as transition resistance, lightning stroke, fault type, load current and operating mode of power system.

A programmable slew rate allows a controlled transition from one load setting to another to minimize induced voltage drops on inductive power wiring, or control induced transients on a test device.
