| Apr 19, 2022 at 15:21 | comment | added | SKGadi | @user3425949, I am using a current transforme. Here the link to the transformer details. micro-transformer.com/2ma-2ma-voltage-transformer-ZMPT101C.html | |

| Apr 19, 2022 at 15:16 | comment | added | user3425949 | What is the transformer ratio? Also, in words, what are you trying to do with the stepped down voltage? As for safety, you need 2 types, overcurrent and overvoltage. | |
| Apr 19, 2022 at 15:11 | comment | added | SKGadi | @Kartman, I want to measure the voltage and see its waveform. | |
| Apr 19, 2022 at 15:08 | comment | added | Kartman | If you want to measure mains, use a mains metering ic. It does all the hard work for you. | |
| Apr 19, 2022 at 15:04 | comment | added | SKGadi | @Kartman, around 255AC is the nominal voltage between lines. However, I am using a 300V to make sure even a slight increase in voltage could be measured. Also, I haven't worked on the protection part yet. Now I am working on the measuring part. Do you think varistor is sufficient as protection? | |
| Apr 19, 2022 at 15:01 | comment | added | Kartman | Where is the 300VAC coming from? There is no input protection so this would be a problem when measuring mains voltages. | |
