Automatic Power Factor Controller Panel is a type of electrical cabinet that is installed together with the MSB cabinet or installed separately in the electrical engineering room or right at the substation for the purpose of improving the cosφ factor. for the power system.
The cabinet usually uses compensating capacitors controlled by automatic compensation controller through contactor switchgear. Depending on the technical design at each project that has a suitable APFC control cabinet, it is possible to use common oil or dry capacitors from 5KVAr to 50KVAr in combination with the corresponding reactor to reduce harmonics. The cabinet can be used in 2 modes Man / Auto through the capacitor controller.
The electrical cabinet is designed in the form of a module, in which the switchgear, functional modules, and busbar system are arranged aesthetically and reasonably to facilitate the installation at the construction site and the upgrading as well. as the operation of the user unit. KVAr parameters depend on the design of each type of construction and still comply with IEC 61439 standards.
Compensating capacitor cabinets are often used in constructions: Industry, factories, Commercial centers, Buildings, Apartments,…
