The intelligent element

The reactive power regulator is, together with the capacitors and reactors (in detuned filter cabinets), the key component of the automatic power factor correction system. It is in fact the “intelligent” element, responsible for the verification of the power factor of the load, in function of which controls the switching on and off of the capacitors batteries in order to maintain the power factor of the system beyond the target.

The reactive power regulators RPC are designed to provide the desired power factor while minimizing the wearing on the banks of capacitors, accurate and reliable in measuring and control functions are simple and intuitive in installation and consultation.

The flexibility of ICAR regulators allows you to modify all the parameters to customize its operation to fit the actual characteristics of the system to be corrected (threshold power factor, sensitivity of step switching, reconnecting time of the steps, presence of photovoltaics, etc.).

They also offer Power Quality functionalities: current and voltage THD, with detail of the single harmonic.

Description

RPC 8BGA reactive power regulator

The RPC 8BGA reactive power regulator equips MULTImatic automatic power factor correction systems.

Exclusive features:

High electrical performance: The 8BGA controller is equipped with powerful hardware, which allows a considerable electrical performances: it can be connected to the CT secondary 5A or 1A, it can work on networks with voltages from 100 to 600Vac with a measuring range from 75VAC to 760VAC, it can be connected to a single CT (typical configuration of the power factor correction) or three-CTs (for a more accurate measurement of the power factor, and this fact makes the 8BGA controller to refocus and to be a multimeter as well).

Extended Capabilities:  8BGA regulator can work master-slave functions, handles up to 10 languages simultaneously, can be used in MV systems managing the transformation ratio of the VT, it can support multiple inputs and outputs via optional modules, it can handle target cos phi fr om 0.5 inductive to 0.5 capacitive. 8BGA can build a network of 4 wired units (one master three slaves) to be able to handle up to 32 steps of power factor correction in a consistent and uniform way.

Graphical display with high readability: forget the regulators with small displays and difficult to read: 8BGA will amaze you with its display matrix graphic LCD 128×80 pixels. The detail and sharpness allow intuitive navigation between the diff erent menus, represented with text and icons.

Advanced communication: 8BGA born to be a regulator able to communicate in a manner in line with the latesttechnology: Ethernet, RS485, GSM / GPRS modem, USB, WIFI.

Evolutivity: the “basic” 8BGA regulator can be enhanced with up to four additional modules “plug and play” which greatly expands its performance. And ‘possible to add additional control relays (up to a total of 16), even for a static control (thyristors), digital and analog inputs, analog outputs, communication modules. Your controller can become a small PLC, and the PFC system can become a point of data aggregation, for remote communication.

Language of choice: 10 languages available on board!

Measurement functions

The measured parameters are the basic ones (cos phi, FP, V, I, P, Q, A, Ea, Er) with the addition of the distortion of the voltage and current (THD, histogram of the value of each harmonic, waveform graphic visualization). 8BGA measure and count values that can help in ruling the PFC (temperature, number of switching of each step). 8BGA also suggests the maintenance to be carried out by means of simple messages on the display. Keep efficient capacitor becomes much easier. 8BGA stores the maximum values of current, voltage, temperature, each associated with the date and time of the event for a better analysis of what happened.

Alarms

The set of alarms (maximum and minimum voltage, maximum and minimum current, over and under-compensation, overload of the capacitors, maximum temperature, microinterruption) associated with the readability of the messages on the display allows a better understanding of what happened. Even alarm programming (enable / disable, delay, relapse etc.) is easier and faster.

Reactive power regulator RPC 8LGA

Reactive power regulator RPC 8LGA equips MIDImatic systems, it is managed by a microprocessor and offers many features maintaining a simple user interface locally or from a PC. They are characterized by a large LCD display with text messages (in 6 languages: ITA, ENG, FRA, SPA, POR, GER) and icons for quick and intuitive navigation.

The regulators have standard temperature control and the ability to configure one of the available relays for activating

visual alarms sound at a distance; also control the distortion of current and voltage.

Regulators RPC 8LGA can operate in automatic or manual mode.

Measurement functions

Regulators 8LGA provide many standard measurements in order to check and monitor the correct electrical and temperature conditions of the power factor correction system.
