Jammers detection devices. Jammer vs meter - tests 30 types of electricity meters

An unusual direction finder, a smart RF detector or indicator, and electricity meter tests are the subjects of this video. The reason for the development was the Jammer, a device for stopping meters with strong radio-frequency fields. Resourceful technicians use anything they can get their hands on to make them, even electricity meters.
Pulse jammers are hard to detect. An unusual direction finder to search for pulse jammers is shown and brief characteristics of this direction finder are given.
Electromagnetic field indicators are sometimes triggered falsely by interference - lightning, a sparking electric razor, a neighbor's amateur radio station. Clever cheap electromagnetic field indicator (detector) is free of this disadvantage.
The results of testing with jammers dozens of types of meters. About the shortcomings of regulations and methods of testing electricity meters
The video may be useful for specialists from Itron, Landis+Gyr, Iskra, Anritsu, for power supply companies, as well as for anyone interested in the problems of electromagnetic fields impacts on electronic devices.
