Hi 2MVAr,
1-If you havebalance loads,the system would work normaly even no grounded points any where .
2- If you have unbalace loads and multiple grounded points are there , the system would work normaly in condition that source neutral is grounded.
3- If the source neutral point is not...
Hi Skogsqurra ,
thanks so much about your nice idea,Iwould know more about comparator property and is it possible to build it my self cause I can not find such component here due to our hard situation .
Hi Skogsqurra I appreciate you respone . It seems to me you did n't get the point,due to shortage of power in IRAQ my home feeded from private power provider 220 volt ac max. 3 amp. and they limit the power by using miniature c.b and fuse , if we consume more than 3 amp. c.b or or fuse will act...
Thank so much about your response.
I want to switch off 220 volt ac for over current of 3 amp,the time of this switch off device should be less than of miniature C.B or fuse time .
Hi ,
What code no. of thyristor can be used to protect 220 volt ac 3 amp power source from over current by using thyristor with gate voltage which makes it off not more (5-9)ac volt
note : I want to build this circuit
