Abstract: Along with the extensive application of nonlinear load, the problem of quality of electric energy became strictness increasingly. On the basis of essentiality of measurement of harmonic of electrified wire netting, the paper looked back developed history of measurement of harmonic in electrified wire netting at home and abroad, analyzed some characteristrics of measuring principle of harmonic in electrified wire netting, gave deve-loping prospect of measuring technology of harmonic of electrified wire netting in our country.
