Compensation Switchboards
The company has long collaborated with customers to solve problems in the field of reactive power compensation. The offer includes an analysis and, based on knowledge of the properties of the electrical distribution network, we can develop corrective solutions for its optimization and trouble-free, economical operation.
The manufactured assortment is based on a variable range of compensators. Switchboards are dimensionally adapted for connection to existing equipment and technically correspond to the working location and operating conditions, including the influence of higher harmonics.
Power factor compensation options:
- Classic contactor compensators with automatic connection of capacitors to the network. The solution is suitable for networks undisturbed by higher harmonics. The disadvantage is the possibility of overloading compensation capacitors and possible increase in harmonic components in networks with their occurrence.
- Protected compensators with a series LC circuit. L chokes in these circuits are tuned to 189Hz as standard (damping factor p=7%). The capacitor is protected against overload thanks to the compensation choke. There is no increase in the content of harmonic components in the network.
- Contactless protected compensation with switching of batteries using semiconductor switches switching at zero and is used in networks loaded with large pulse consumptions (welding machines, presses, etc.).
- Decompensators with stages consisting of contactors switching decompensation chokes, their regulation is controlled by a special unit.
