Measurement details •Dielectric breakdown voltage (unit: kV)
Voltage when a dielectric breakdown occurs in the test piece under the specified
test conditions
The median, average, and standard deviation are displayed.
•Dielectric breakdown strength (unit: kV/mm)
Value obtained by dividing the dielectric breakdown voltage by the distance
between two electrodes used for a test
The median, average, and standard deviation are displayed.
