Development of drawings illustrating waveforms enrich the state by working with the load, the load is decreased, the state shut down the equipment in the plant, commissioning of individual machines and re-load status. Included in the individual states and the compensating capacitor banks excluded. We analyzed the current and voltage signals in the context of the harmonic content, set the value of THDi and THDu factors.engReactive Power CompensationVoltage and Current DistortionHigher HarmonicsFrequency Converterarticle
