I am using Cadence-Orcade Lite. In it I have a circuit in which I want to note the behaviour of varistors (MOV, PSPICE models exist in Orcade for various varistors).
I am using LS40K680QP/EPC Model of a varistor and I want to depict the behavior of this device when transients in ac supply are applied.
I have connected an ac source in parallel with some load. When I simulate it, it doesn't have any effect on signal voltages even when the voltages are beyond its clipping voltage (or rated voltage from datasheet). It should clip voltages to the maximum operating voltage of varistor when supply voltage have transients in kilo volts.
I want to know, if there is some method to make this mov depict its actual behavior, or does it just not simulate real life?
