Experimental Study on Static Electricity Meter Performance with the Permanent Magnet
To suppress the use of all kinds of magnetic interference electric energy meter for stealing electricity,this paper analyzes the permanent magnet character captured from the suspect in the lab conditions and the interferential test is carried on static electricity meters which are used widely with these magnets.Experiments show that the permanent magnet for electric energy metering performance have a great effect.On the basis of experiments,the electric energy meter is developed,which can detect a constant magnetic field and an alternating magnetic field interference and has the real time alarm function.The meter has ran for more than a year to get great benefits.
