Lightning Surge
Lightning surge resistors are tested in accordance with IEC 60 115-1 using both 1.2/50µs and 10/700µs pulse shapes. 10 pulses are applied. The limit of
acceptance is a shift in resistance of less than 1% from the initial value.

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
