Single Impulse
The single impulse graph was the result of 50 impulses of
rectangular shape applied at one minute intervals. The limit of
acceptance was a shift in resistance of less than 1% from the
initial value. The power applied was subject to the restrictions
of the maximum permissible impulse voltage graph as shown.
Continuous Load Due to
Repetitive Pulses
The continuous load graph was obtained by applying repetitive
rectangular pulses where the pulse period (tp) was adjusted so
that the average power dissipated in the resistor was equal to
its rated power at 70°C. Again the limit of acceptance was a
shift in resistance of less than 1% from the initial value.
The formula used to calculate the average power for repetitive
pulses is shown below.
