Capacitors used for compensation are connected in parallel to the network in inductive reactive power characteristic enterprises, where loads such as motors, transformers, and coils predominate. They prevent the drawing of inductive reactive power from the grid and avoid potential penalties due to reactive power rates. These capacitors are designed and implemented to compensate for the reactive power of the facility in various fixed or automatic applications depending on the load condition.
• Sigma Low Voltage Power Capacitors offer reliable and long-lasting solutions for the reactive power needs of compensation systems, ranging from 0.25 kVAr to 5 kVAr in 230V single-phase capacitors, from 0.5 kVAr to 50 kVAr in 400V, 415V, 440V three-phase capacitors, and from 10 kVAr to 30 kVAr in 525V heavy-duty capacitors.
• Sigma capacitors ensure rapid discharge through internal discharge resistors.
• Sigma capacitors feature overpressure protection; in the event of excessive pressure, the separation wire inside the capacitor breaks, cutting off energy transmission and providing safe protection.
• Sigma capacitors are manufactured with dielectric polypropylene film material, ensuring low loss and long life.
• They have significantly lower power losses than those specified in TS EN standards.
• They provide safe operational performance even at ambient temperatures up to 65°C.
