The invention discloses radio frequency electromagnetic field radiation immunity experiment test device and test method for an electric energy meter. An electric energy meter inspecting device, a communication and display device, a signal generator, a power amplifier and an emitting antenna are connected in sequence, and a main controller is connected with the communication and display device. During test, the electric energy meter inspecting device provides a voltage and current signal needed during the working of a tested electric energy meter and obtains an electric energy meter error value; the signal generator generates a frequency signal required by the test standard; after being amplified by the power amplifier, the frequency signal is transmitted to the emitting antenna, and an uniform field required by the test standard is generated by the emitting antenna; and the communication and display device is respectively communicated with the electric energy meter inspecting device and the signal generator by steps and reads, records and displays frequency information in the signal generator and electric energy meter error value information in the corresponding electric energy meter inspecting device. The invention can automatically record the test frequency and the corresponding electric energy meter error value and can obtain more complete and accurate test data.
Description
technical field [0001] The invention relates to an electric energy meter radio frequency electromagnetic field radiation immunity test device. Background technique [0002] At present, the known test device for the radio frequency electromagnetic field radiation immunity test of the electric energy meter is composed of the electric energy meter inspection device, a signal generator, a power amplifier and a transmitting antenna. During the test, the testing device of the electric energy meter provides the voltage and current signals required for the work of the electric energy meter under test, and obtains the error value of the electric energy meter. The signal generator generates the 80MHz-2GHz frequency signal required by the test standard, and after being amplified by the power amplifier, the uniform field required by the test standard is generated by the transmitting antenna. However, the energy meter standard requires that the test frequency and the corresponding error...
