Power Factor Improvement Panel

A capacitor compensation panel is used to improve power factor in electrical power systems by compensating inductive loads. It operates by connecting capacitors in parallel, which offsets inductive current. As a result, the power factor is improved, line losses are reduced, and voltage quality is enhanced. The rated voltage is AC 6kV or 10kV. The core component is the capacitor, which stores electrical energy. Contactors are used for fast switching of capacitor banks. This power factor improvement panel is also equipped with overvoltage, overcurrent, and short-circuit protection, ensuring safe system operation.

A low-voltage capacitor compensation panel consists of a cabinet, busbars, fuses, capacitors, reactors, and an automatic power factor controller. Several models are available: ES-2010 for thyristor zero-crossing switching, ES-2011 for harmonic suppression, ES-2012 using metallized film capacitors, and ES-2013 for fixed compensation. This power factor improvement panel is suitable for low-voltage dynamic compensation, high-voltage automatic compensation systems, large motors, and substations with stable loads. The container-type outdoor version features a compact structure designed for sea transport and fast on-site installation.

Many customers ask about operating temperature limits. The capacitor in this power factor improvement panel is designed for an upper ambient temperature of 40°C, while the internal dielectric medium temperature should not exceed 70°C. The rated voltage remains AC 6kV or 10kV. Fast switching is achieved using contactors. Protection functions include overvoltage, overcurrent, and short-circuit protection. This product is manufactured in-house, ensuring full quality control. Samples are available upon request. We provide a 1-year warranty with reliable after-sales support.
