ELEKTON-RPC Reactive Power Compensator

Purpose and application

ELEKTON-RPC reactive power compensators are designed to compensate for the inductive component of reactive power consumed by the load.

Reactive power is compensated by connecting delta-connected capacitors parallel to the load.

The highest efficiency of RPC application is achieved by connecting it directly to 0.4 kV buses of the transformer substation. This ensures compensation of reactive power of all inductive loads connected to such substation. An RPC may also be connected to the input terminals of the switchboard.

Functional capabilities

The reactive power compensator reduces current loads on powerlines, transformers and distribution equipment that helps reducing power losses. RPC ensures automatic reactive power compensation as per the controller’s setpoint entered in the preset mode.

RPC is contained in a front access welded cabinet. The cabinet has capacitors, contactors, circuit breakers, a disconnector switch with fuses, and a controller on the control panel.
