fields, for which a completely new measuring technology is
required for the high-frequency radiation.
Comments on Measuring Technology
For a meaningful measurement, the following minimum
requirements on the measuring technology for low-frequency
alternating fields were setup in the SBM2008:
• Potential-free measurement of AC electric fields.
• Reproducible, high accuracy.
• Compensated frequency response over the entire specified
frequency range, which should go at least from the railway current
frequency with 16.67 HZ to the kilohertz range.
• High resolution: 0.1 V/m or better.
The measuring devices of ROM-Elektronik can meet all these
requirements.
Preparation of measurement
1. Check the measuring device in accordance with the instructions
in the chapter "Before setup".
2. Beforehand, a measurement of the AC electric field is to be
conducted outdoors in order to determine the basic load. If a
basic load over 2 V/m is displayed, a classification of the basic
load can be performed beforehand. Switching off the circuits by
means of the automatic circuit breaker in your own house fuse
box determines which fields are from the house and which are
from other field sources, for example, generated from high-
voltage lines, railway power, transformers or installations
adjacent neighboring homes. If external field sources are
responsible, higher field strengths can be localized there.
