Single Impulse
The single impulse graph is 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 grpah was
obtained by applying repetitive
rectangular pulses where the pulse
period 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.
