Power SupplyAll plants associated with power supply, such as high-voltage power lines and transformer stations, are regarded as LF radiation sources; transmission equipment on high-voltage masts can be HF radiation sources. | |
Power supply plants | |
Measurement task: | Measure and record field strengths to establish proof of emission levels to customers and authorities. |
Frequency range: | 16 2/3 Hz (railroad), 50 Hz, 60 Hz |
Transmission installation on HF masts / towers | |
Measurement task: | For transmission equipment on masts / towers, personal monitors are recommended. |
Frequency range: | 30 MHz ... 5 GHz |
Railway: Power Supply Plants | |
Measurement task: | Prove safety for personnel, magnetic fields can interfere with safety or IT plants and systems. |
Frequency range: | 16 2/3 Hz, 50 Hz, 60 Hz, 400 Hz (ships, aircraft) |
Railway: Communication Systems | |
Measurement task: | The railway's own communication systems have to be certified with appropriate HF measurement technology and checked regularly. |
Frequency range: | 30 MHz ... 3 GHz |
