Power Capacitor Units for improved power quality

Applications for capacitors Reactive power compensation Most of the apparatus and loads connected to the electrical power system consume both active and reactive (inductive) power. Some examples of such components are transformers, transmission and distribution lines, induction motors, rectifiers, induction furnaces, etc. The most economical method of reducing reactive power consumption in electrical power systems is by installing capacitor banks. This method is called reactive power compensation. The capacitor injects reactive power into the system, thus reducing the load in the entire...

Fusing technologies Impregnated capacitor unit — CHD The CHD type is a single-phase power capacitor of the all-film type, with low dielectric losses and long service life. The capacitors are impregnated with Faradol, a bio-degradable product with high insulation strength. The edges of the electrode foils are folded, enabling higher electrical stress. The ABB capacitor units have an extremely low failure rate and high reliability. The CHD capacitor unit is made up of a number of elements, each consisting of very thin layers of dielectric materials and thin foils of aluminum as electrodes....

Testing equipment Portable capacitance meter, CB-2000 The CB-2000 is an advanced measurement instrument characterized by its compact design and low weight, which makes it easy to carry when conducting measurements. No disconnections in the capacitor bank or mains connection are required. The collected measurement values can be easily transferred to a PC for storage and analysis. The stored values from the PC can just as easily be transferred to the meter so that they are available when new measurements are made. Measuring capacitance is an important part of the regular maintenance of...
