Dialetric breakdown data

Description

The dialetric breakdown strength of electrical insulation

Usage

data(breakdown)

Format

A data frame containing 128 observations with the following 3 variables.

Strength

the dialetric breakdown strength, in kiloVolts

Time

the time exposure in weeks; one of 1, 2, 4, 8, 16, 32, 48, or 64

Temperature

the temperature, in degrees Celsius; one of 180, 225, 250 or 275

Details

The data come from a study of performance degradation of electrical insulation from accelerated tests. The study can be considered as a 8-by-4 factorial experiment, with four measurements for each time–temperature combination.
