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.
