High-Voltage Test Workload at 68% target hv test coverage: a worked example

Suppose target hv test coverage falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate high-voltage test coverage from units requiring hipot or insulation test, total units built, and the target coverage percentage.

The inputs for this scenario

  • Units scheduled for HV test: 8 units (held at the documented default)
  • Total units built or released: 250 units (held at the documented default)
  • Target HV test coverage: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: High-voltage test workload rate = units scheduled for HV test ÷ total units built or released × 100.
  • High-voltage test coverage works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • HV test coverage gap works out to 64.8 points at these inputs.
  • Units scheduled for HV test works out to 8 count at these inputs.
  • Total units built or released works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target hv test coverage sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the percentage of built units scheduled for HV test and the point gap to your target coverage. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • High-voltage test coverage: 3.2 % (headline result)
  • HV test coverage gap: 64.8 points
  • Units scheduled for HV test: 8 count
  • Total units built or released: 250 count
