I am using a meganetic field meter(Trimeter) to measure the EMF in my house.
There is a pipe in the crawl space which is measured to be 25mG if I put the meter on it. It is 8mG one foot away. Let me call it pipe #1. The pipe #1 is small and is connected from Garage to swimming pool pump. It goes underground in the yard. I guess there are electricity wires inside the pipe because there is a box connected it which is supposed to be a wire box. Unfortunately, the pipe is just below two bedrooms. So the EMF readings in the two bedroom are about 3mG in many spaces.
So I decide to fix the problem. however, when I turn off the main power at the panel, the EMF reading of the pipe is not changed at all. I am sure the power to the house is cut off because the reading on PG&E(the utility vendor) meter is 0W. I also measured another pipe under the PG&E meter. let me call it pipe #2. It is 50mG if I put meter on it. The pipe #2 is supposed to carry electricity wires from street to the house. There is a small strand connecting the panel to the pipe. I guess the strand is a ground wire.
I measured the waterpipes in bathrooms. there is no big readings as pipe #1.
I need some help now.
1 After I turn off the panel, it is supposed that both pipe #1 and #2 to be 0 current on ground wire and other wires. So the EMF reading should be much less around the pipes. Is my understanding correct?
2 As I can still observe EMF on the pipes, I guess there is ground current on the pipes. Is there any other possibilities to have the same phenomena?
3 Is it useful if I add more ground electrodes in garage and crawl space and connect the pipe #1 to these ground electrodes?
4 Should I buy clamp meter to measure the current? I think the EMF meter has the same work function as clamp meter. so is it necessary?
thanks ahead
