Abstract: A computerized simulation validating method for a full-scale distribution network single phase-to-ground fault test is implemented by simulating a full-scale test system with external quantities being controlled to be conformant and validating the full-scale distribution network single phase-to-ground fault test based on a conformance check result between the internal quantities of the field testing and the internal quantities of the simulation testing. The simulation validating method for a full-scale distribution network single phase-to-ground fault test improves normalization and conformance of the full-scale distribution network ground fault test. The computerized simulation validating system, apparatus, and medium for a full-scale distribution network single phase-to-ground fault test also achieve the benefits noted above.

Abstract: A multi-slope load/unload ramp for a hard disk drive includes an inner first portion having a non-horizontal first slope and an adjacent outer second portion having a different non-horizontal second slope. The first slope may be steeper than the second slope, and the ramp may further include a third portion adjacent to the second portion and also having a third slope steeper than the second slope, with the ramp configured for positioning the first and second portions to overlap the disk while the third segment may be in part outside the disk. The second slope may be steeper than the first slope, with the ramp configured for positioning the first portion to overlap the disk while the second portion may be in part outside of the disk. Hence, any slider rebound from the steeper portions would occur outside of the disk and avoid a slider-disk crash.
