Power factor correction equipment provided under other sections of the specifications as part of other equipment shall comply with this section. Related Sections. References.
Individual power factor correction is achieved by connecting capacitors directly to the terminals of motors, transformers and other loads. In this manner the network avoids distributing the reactive power absorbed by load. Individual power factor correction capacitors reduce additional losses caused by cable and transformer coil heating, and allows for the installation of smaller sized
These instructions must be read carefully before unpacking, installation, operation, and maintenance of this bank. Eaton''s Unipak, Unipump, and Unipak filter series fixed power factor capacitor banks are intended for correction of (displacement) power factor at and upstream of the connection point of the capacitor bank.
Low voltage capacitors are considered a low cost, high reliability and maintenance free means of providing the needed kilovars. Capacitors can efficiently supply the reactive current to inductive loads, so those kilovars do not have to be sent all the way from the utility generator to the inductive loads. This relieves both your electrical
