Recording Interharmonics with the Revolution

Category: ProVision, Revolution, PMI Products, Box Recorder, Harmonics/Interharmonics, Using PMI Recorders

Interharmonics are on the rise because of large non-linear loads and sources being introduced to the distribution network, in particular large Variable Frequency Drives (VFDs) and inverters for distributed generation. Interharmonics are very complex, making them harder to measure and analyze than some of the other power quality issues. In this paper I will cover how interharmonics can be recorded, measured and analyzed with the use of PMI’s Revolution power quality recorder and Provision software.
