Introduction:

There are many low-frequency field strengths present in our living environment, and any place where electricity is generated, transmitted, and used will generate low-frequency electric fields, such as homes, workplaces, medical equipment, and even outdoor high-voltage transmission lines will generate electric fields. Wherever there is high current, there is a magnetic field; wherever there is high voltage, there is an electric field. It is almost impossible to completely avoid the influence of electric fields. It is important to understand their impact on us and reduce it through certain meanselectromagnetic radiationThe impact.

Applicable standards:

GBZ/T 189.3-2018 "Measurement of Physical Factors in the Workplace";

GB 8702-2014 Electromagnetic Environment Control Limits;

EN V 50166, EN 50366, BImschV, DIN VDE 0848, BGV B11, etc.

The relevant measuring instruments corresponding to these specifications should consider the following aspects:

• In order to obtain and establish the true response of the human body in electromagnetic fields, monitoring instruments should have isotropic and real-time functions, and must be able to simultaneously measure the values of electric and magnetic fields, as electromagnetic fields act on the human body simultaneously.
• The measuring coil must be small enough to accurately transmit measurement results even in close proximity to the magnetic field source, minimizing introduced errors.
• Because various fields can generate fluctuations, and many limits depend on time accumulation. So, it is meaningful to record for 24 hours without a computer. Therefore, measuring instruments must have sufficient continuous measurement time and large storage space.

Low frequency field with frequent occurrences:

• Power station and transformer
