GS, CS banks are purposely designed as fixed P.F.C. equipment, which represent the ideal solution to compensate for both constant loads and transformers. They can completly eliminate charges made by Electricity Authorities because of the low power factor. They can also considerably reduce the loading and thus the heating and voltage drop losses, this allows the ebst utilization of existing power lines. The CS-AAR model is manufactured in sheet steel and equipped with henadles for easy handling and mounting. The capacitors used are self-healing metallized polypropylene and equipped with a pressure sensitive disconnector. Their reliability is recognized by IMQ standards (MK-AS type). For application in the presence of high harmonic distortion, banks equipped with detuning reactors are available (AAR/100 type). These reactors are manufactured using low loss magnetic cores with high linearity. The tuning frequency is 189Hz
