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.

Continuous Load Due to Repetitive Pulses

The continuous load graph 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

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 shown.

Continuous load due to

repetitive pulses:

The continuous load graph

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.
