Engineered for superior performanceand long-term value

The entire VarSet range offers a unique,

simple, cost-effective, wall-mounted

capacitor system that will help reduce

your utility bills and will not take up any

floor space in your electrical rooms.

Unlike standard floor-mounted systems

that take up floor space, these systems

can be mounted above existing

equipment or on any free wall space.

Construction of References —Principle

Devices using power electronics (variable speed drives, rectifiers, UPS,

arc furnaces, fluorescent lamps, etc.) generate harmonic currents in

electrical networks.

Such harmonics can interfere with the operation of many devices, including

capacitors, which are highly sensitive to harmonics.

A high level of harmonic pollution causes capacitors to overheat and age

prematurely (breakdown).

Different types of compensation must be chosen according to the power of

the harmonic generators: standard or detuned. It can be selected as follows:

A Current Transformer Is Required For Automatic Control

In order to have automatic control, a current transformer must be ordered in

addition to the PFC bank.

A current transformer (not included) is necessary to provide accurate

network information to the VarSet’s controller in order to apply the correct

quantity of kVAR at any given time. It is recommended to choose a Split Core

Current Transformer Model 270R from the following list of options.

Note: CT must be sized to your network and have a secondary rating of 5A.

More details on the CT can be found in document 4210CT9701.

Step Circuit Breaker

Each physical step is protected by a step circuit breaker that ensures that

our equipment is highly fault-tolerant, ensuring continuity of service even

when one or more capacitors are malfunctioning. This superior protection

provides a stage overload protection that cannot be achieved with HRC

fuses, furthermore it eliminates the need for spare fuses. The details of the

steps are on page 9.

Incoming Circuit Breaker

Square D by Schneider Electric circuit breakers are designed to ensure

maximum continuity of service. Our VarSet range of products has the option

of being protected with an incoming circuit breaker. Our range comes with

an option to integrate circuit breakers of 65 kA breaking capacity for 480 V

networks and 50 kA for 600 V networks. Rotary handle is also provided to

facilitate the disconnection of circuit breakers before opening the door. This

is an additional protection mechanism to ensure personnel safety.

Varlogic N Power Factor Controller

Our range of Varlogic N series of Power Factor Controllers are simple to

program, reliable, and intelligent. Varlogic Controllers offer user-friendly

features such as a large backlit display, intuitive menus, ergonomic layout of

buttons, direct display of main measurements, and intelligent self set-up.

The Varlogic N Controllers constantly measure the reactive power of the

installation, and control the connection and disconnection of capacitor steps,

to obtain the required power factor. The range is composed of:

p NR12: control up to 12 capacitor steps

p NRC12 with modbus: control up to 12 capacitor steps, with advanced

diagnostic functions and integrated modbus interface communication

module, which enables Varlogic functions to be connected to the energy

server EGX300. The EGX300 is an integrated gateway-server that requires

only a Web browser and Ethernet network to log and display real-time data

and trend plots.

Auxiliary Transformer

Auxiliary units, such as contactors, controllers, and fans, operate only on

120 Volts AC. The voltage for the auxiliaries has to be converted by an

auxiliary transformer. In order to simplify the installation process, VarSet

equipment comes with an integrated auxiliary transformer.

Other Accessories

Accessories, such as plinth (for easier installation on uneven surfaces,) canbe ordered as an option along with the VarSet equipment.

VarPlusCan: Heavy Duty Capacitors

The VarSet range of equipment is integrated with heavy-duty aluminum

can capacitors (VarPlusCan) that are specially designed and engineered

to deliver reactive power continuously with low losses.

Features:

p continuous service

p high overload capabilities with good thermal and mechanical properties

p self-healing with discharge resistors

p pressure-sensitive disconnector on all three phasesp special film resistivity and metallization profile for higher thermal efficiency

and enhanced life expectancy

TeSys Contactors

Capacitor control is accompanied by a transient state resulting from the

capacitor load. This generates a very high overcurrent, equivalent to a short

circuit of short duration.

Unique technology contactors

The contactors used in our devices are specifically designed for capacitor

control. They are fitted with a contact block allowing the current to pass on

closing through damping resistors that limit the current on energization.

Personal safety

The contactors cannot be operated manually. The contactors are fitted with

covers to protect them from direct contact.

Safety of installations

Damping resistors are used to reduce transient over-voltage.

Continuing service life

These contactors are a ready-to-use solution that avoids the installation

of inrush reactors. Their service life is far longer than that of conventional

solutions.

Detuned Reactors

Detuned reactors enable the protection of capacitors against harmonics.

They are recommended for usage in harmonic-rich networks, and come with

4.2 p.u. tuning order.

They are equipped with a thermal protection device for step disconnection.

Spatial Enclosures

p IK10: Maximum possible protection against mechanical shocks and can

Schneider Electric, thus ensuring high quality.
