The issue of excess reactive power is becoming increasingly critical in the industrial sector. Its accumulation leads to overloading electrical network equipment, increased energy losses, and significant financial costs. One of the most effective ways to keep the electrical system running smoothly is to use a Reactive Power Compensation Cabinet (RPCС), which is a specialized electrical system that improves the grid's performance. This type of equipment belongs to the category of “Industrial Products”.

RPCC Functions and Operating Principles

The Reactive Power Compensation Cabinet is used to stabilize the power factor (cos φ) in three-phase distribution networks with an operating voltage of up to 400 V and a frequency of 50 Hz. Due to its operating algorithm, the RPCC automatically maintains the required cos φ value regardless of load fluctuations.

Main Tasks of the RPCC:

  • Ensuring the required power factor of consumer equipment (within the range of 0.8–1.0), i.e., the reactive power of the enterprise.
  • Improved stability and quality of electric power.
  • Significant reduction in electric power costs by reducing inefficient consumption.
  • Reduced load on the network infrastructure, which has a positive impact on its service life.
 

Where are Reactive Power Compensation Cabinets Used?

Both RPCC and relay cabinets are used in all types of industrial and commercial electrical networks. The most common areas of application are:

Industrial enterprises
and production lines

иконка

Substations
and power centers

иконка

Data centers

иконка

Infrastructure facilities
(hospitals, airports, residential complexes)

иконка

Systems with high starting
and inductive loads

The RPCC allows you to avoid penalty charges for low power factor and improve the energy efficiency of the entire system.

 

Main Purpose

The RPCC main purpose is to compensate for reactive power in the electrical networks of enterprises. The system minimizes unwanted loads and stabilizes power supply parameters by automatically connecting or disconnecting capacitor unit(s).

The operating principle is based on:

  • Analysis of load modes received by the network,
  • Automatic adjustment of compensation levels,
  • Stabilization of the power factor (cos φ),
  • Reduction of currents in lines and electric power losses.
