7 14. Lightning Surge Resistors are tested in accordance with IEC using both 1.2/50us and /700 pulse shapes. The limit of acceptance is a shift in resistance of less than 1% from the initial value. /700us Lightning Surge 00 Peak voltage (votts) Resistance (ohms) 1.2/50 us Lightning Surge 00 Peak voltage (votts) Resistance (ohms)

8 15. Pulse withstand capacity 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. 0 Single Pulse( ohm) Power (Watts) Time(sec.)

9 16. Continuous Pulse 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. 00 Continuous Pulse ( Ohm) 0 Pulse Power P(W) Pulse Duration time (s) Pulse Voltage( ohm) 00 Pulse Voltage (Volts) Pulse Duration time (s)
