Single-phase and three-phase chokes with iron cores produced by Elhand Transformatory are ideal for harsh operating conditions in numerous industrial applications. They are used in systems with capacitor batteries as smoothing chokes or filtering chokes. They also operate as shunt reactors to compensate capacitive reactive power of power lines or as limiting chokes that reduce the value of short-circuit currents. They may also operate as limiting chokes that limit the steepness of voltage rise du/dt or current rise di/dt. The use of modern components and technologies in the manufacturing process combined with innovative design solutions, can meet the highest standards of quality and reliability. The introduction of standardization of production, simple and ergonomic solutions make the devices user-friendly, easy to install and requiring no additional maintenance during their operation. We produce chokes according to the individual customer's specifications.
