If someone has one please share it with me.

Thanking you before hand.

Re: How to build an Earth (Ground) Resistance Continuous Monitoring Device?

Hi,

I am looking for an Earth Resistance Continuous Monitor Device operating on 230VAC 50HZ to verity the Earth/Ground (TT system) every second. In case the resistance drops below the parameter (25~100 ohms), a visual (LED) is lighted plus an audible alarm is heard.

Refer to link below:

Hope this link will be self explanatory.

Thanks.

Regards,
