Abstract
Most of complaints about power frequency electromagnetic fields of the substation and lines by the public are based on test results of pow er frequency electromagnetic fields around the substation and lines by using the simplified electromagnetic field tester, w hile there are great differences in test results respectively by using the simplified tester and the kind of conventional electromagnetic field tester specified in standard regulation.Therefore, this paper introduces producing principles of pow er frequency electromagnetic fields of the substation and lines and evaluates properties of eight kinds of simplified electromagnetic field testers.On the basis of field test in the electromagnetic environment around the substation and lines, it discovers large differences in test results.The results indicate the maximum discrepancy of detection results of pow er frequency electric field is nearly to one time w hile that of pow er frequency electromagnetic field is about fifteen times.In addition, there are great differences in detection results of different simplified electromagnetic field testers, the maximum discrepancy of detection results of pow er frequency electric field is nearly to one time w hile that of pow er frequency electromagnetic field is about fourteen times.Thus, it requires to be cautious about test results of the simplified tester and asks for the conventional tester for measuring accurate pow er frequency electric field intensity and pow er frequency electromagnetic field intensity.关键词
