When the voltage frequency varies, capacitors convert this into a current that varies even more. Books, Literature, and Writing. Users produce harmonic currents that flow through the system owners or operators system which lead to voltage harmonics in the voltages supplied to other users. Tamara Wilhite is a technical writer, industrial engineer, mother of two, and a published sci-fi and horror author.
Users produce harmonic currents that flow through the system owner's or operator's system which lead to voltage harmonics in the voltages supplied to other users. The harmonics should be measured before a piece of equipment is turned on and after has been started up. Because of the nature of the recommendations, some conservatism is present that may not be necessary in all cases. In effect, such actions by a user couldamount to producing excessive voltage harmonic distortion. The limits set are for steady-state operation and are recommended for worst case conditions.
This standard addresses steady-state limitations. The limits in this standard represent a shared responsibility for harmonic control between system owners or operators and users.
