specific Embodiment 1
[0050] figure 1 It is a flow chart of the method for measuring power frequency electric field intensity according to the specific embodiment of the present invention. Such as figure 1 As shown, the method 100 for measuring power frequency electric field strength according to the present invention starts from step 101 .

[0084] Step 1. Measure the diameter of the power frequency electric field probe to 3 cm, and calibrate the probe.
[0085] Step 2. Establish a three-dimensional simulation model of two sets of metal circular pole plates whose radii R are 30cm and 40cm respectively, and which are arranged vertically and horizontally.
[0086] Step 3. Calculate the uniform power frequency electric field theoretical strength E of each group of metal circular plates with a radius R under the condition of different plate spacing H 0 , establish a mapping from (R, H) to (r, H);
[0087] Let R=30cm, H=10cm, applied voltage 480V, theoretically calculated field strength E=480 / 0.1=4800V / m, define a uniform area according to the range of ±3%, that is, the field strength is 4800×(1±3%) The area of (V / m) is counted as the uniform area.
