I'm searching some sort of worst case model of the main electricity 230V-AC. The most simple source is a sine with 50Hz and 325V peak.
But we could have disturbance on the main electricity, and I'm also interested to know if there is a sort of list with "corner model" that can happen?
I can give one disturbance case: Imagine a high power load controlled by a triac (that switch on/off properly at 0 current/voltage). Because the line have a resistance and an inductance, the switch on/off of a high power load will have an impact on the main electricity voltage (325V could become 320V or worst?). If this load is connected an odd number of times, then the injected disturbance will generate a sort of DC voltage/current on all transformer connected on the main electricity line. I want to simulate this with LTspice.
After my example, is there a database of corner model (with this type of disturbance) that can happen on the 230V-AC? A sort of international standard where all tools connected on electrical outlet should pass?
