Measuring and monitoring systems Contents Energy management - Basic knowledge Contents 2 Harmonics 17 Collection of formulas 5 Current / voltage unbalance 24 Current transformer 6 Transients General information on current transformers Selecting current transformers Current transformer construction types Installation of current transformers Operation of current transformers 34 Communication via the RS485 interface 7 Voltage dips and interruptions 42 Ports, protocols and connections 9 Phase shifting and reactive power 44 Overvoltage categories 10 Power factor correction Basics for power factor correction Calculation formula for the capacitor 46 Valid standards 15 RCM Residual Current Monitoring 1 Harmonics Harmonics The constantly rising number of non-linear loads in our power networks is causing increasing "noise on the grid". One also speaks of grid distortion effects, similar to those that arise in the environment due to water and air pollution.Spannungsverlauf Generators (V) ideally produce purely sinusoidal form current at the output terminals. This sinusoidal current form is considered the ideal alternating current form and any deviation from this is designated mains interference. Current progression 2 Stromverlauf (A) An increasing number of loads are extracting non-sinusoidal current from the grid. The FFT-Fast-Fourier-Transformation of this "noisy" current form results in a broad spectrum of...
