The real-time electromagnetic-wave measurement system is a device for the general public’s understanding of electromagnetic fields and for the promotion of such fields. It measures the magnetic field of 60 Hz extremely-low-frequency waves in real time under the power line transmission tower where there is a high general-public traffic and displays it on the LED signboard. At the same time, it compares the real-time electromagnetic-field measurement values with the domestic and foreign standard values and with the average electromagnetic-field measurement values of various electronic products to inform the general public of the electromagnetic-field environments around power lines, with a view to enabling the general public to overcome their vague fear of electromagnetic fields. This system is installed and operated at power line transmission towers with a high general-public traffic.

By measuring the electromagnetic-field environments in residential areas near a power line or in areas where civil complaints have been filed due to a power line to determine the present electromagnetic-field exposure situation, it can resolve the doubts of the residents and civil petitioners about electromagnetic fields.

The measurement of magnetic fields around power lines and the recording of magnetic-field measurements inside factories, power plants, and substations can be expected to contribute to the understanding and purification of electromagnetic environments.
