In a system consist of various harmonics sources, the impact of the harmonics appears on the weakest point of impedance, i.e. on the capacitors in the capacitor banks. Harmonics caused over current and over voltages on the capacitors. In addition, current and voltage distortions caused by resonance that may occur due to the existing harmonics in the system will damage compensation and also cause electronic board failures and power losses.
Asset MS series capacitor banks with harmonic filters have been designed by using 440 V modular units and high technology digital reactive power control relays.
Thus, Asset MS series capacitor banks with harmonic filters operate perfectly and continuously up to 520 V thanks to it is withstand values 18% over voltages and 50% over current.
Inrush current limiting characteristics of Asset R7 series compensation racks help to network to not increase the inrush when capacitor units switched on and occur long life and more safety in all plant by the using of high quality equipments.
Using the Asset R7 series compensation racks in Asset MS series capacitor banks with harmonic filters provides a modular structure to the entire system and allows operator to add and modify the steps very easily and practically.
MS series capacitor banks are switched on/off of their capacitor steps automatically by state of the art digital reactive power control relays. Further to current and voltage information coming from current and voltage transformers, define the required reactive power and switch the steps. Reactive power control relay knows the nominal power of each step and can calculate the reactive power demand, because of this only required steps are switched on/off by relay. Thanks to this, reactive power is provided quickly with less contactor switching and less variation.
