Compensating switchboards are designed to compensate for the consumption of reactive energy to the value of the inductive power factor in the range of 0.95-1. Depending on the extent and nature of electricity consumption, compensation can be solved as central, group and individual, resp. as a combination of individual types of compensation. When designing the compensation device, we recommend based on measuring the quality of the network. Standard networks of compensating switchboards are used in networks without the occurrence of higher harmonics. In networks with the occurrence of higher harmonics, ie where semiconductor-controlled elements occur in the technological equipment of production, it is necessary to use so-called paid (protected) compensating switchboards.
Compensating switchboards are supplied in switchboard cabinets of the US type resp. OCEP (suspended), whose parameters cover a wide range of requirements for the design of a given type of equipment.
An option against the delivery of new compensating switchboards is the installation of new equipment in existing switchboard cabinets. It is also possible to choose a variant of incorporating the compensation part into the RST switchboard.
