Characteristics
Electrical measurements (initial/after tests) shall be conducted at
temperature of 5 to 35 °C, relative humidity of maximum 85 %
The voltage between two terminals with the specifi ed measuring
current CmA DC applied is called Vc or V
should be made as fast as possible to avoid heat effects.
The recommended maximum sinusoidal wave voltage (rms) or the
maximum DC voltage that can be applied continuously.
The maximum voltage between two terminals with the specifi ed
impulse current (8/20 µs).
The maximum power that can be applied within the specifi ed
ambient temperature.
Maximum energy of less than ±10 % of the varistor voltage
change when the standard impulse (2 ms) is applied one time.
Maximum current of less than ±10 % of the varistor voltage change
when impulse current (8/20 µs) is applied twice continuously with
an interval of 5 minutes.
The change of Vc shall be measured after the specifi ed impulse
is applied 10000 times continuously with an interval of 10 seconds
at room temperature.
The change of Vc shall be measured after the specifi ed impulse
is applied 100000 times continuously with an interval of 10
seconds at room temperature.
