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:

Choice of Compensation Type

V L V A W 2 N 6 6 1 0 0 A A

Equipment type Voltage Frequency Power Used to differentiate incomer

VLVAW2N: small-size standard 6 = 480 V 6 = 60 Hz 100 = 100 kVAR AA = lugs

VLVAW3N: mid-size standard 7 = 600 V AB = incoming CB

What are these ratios?> The Total Current Demand Distortion (TDDi)

ratio is harmonic current distortion against the full load (demand) level.

> The percentage of Total Harmonic Voltage Distortion (THD(V)) is measured at the transformer secondary, at maximum load and without capacitors.

A Current Transformer Is Required For Automatic ControlIn 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.

Catalog Number Current Rating *(Amperes)270R-501 500:5270R-102 1000:5270R-152 1500:5270R-202 2000:5270R-302** 3000:5270R-402** 4000:5

Note: When selecting a CT be sure to use proper rating factors for ambient temperature conditions.* Rating Factor 30 °C/80 °F Ambient Temp. = 1.33

Rating Factor 55 °C/131 °F Ambient Temp. = 1.0

Step Circuit BreakerEach 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 BreakerSquare 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 ControllerOur 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 TransformerAuxiliary 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 AccessoriesAccessories, such as plinth (for easier installation on uneven surfaces,) can be ordered as an option along with the VarSet equipment.

and enhanced life expectancy

TeSys ContactorsCapacitor 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 safetyThe contactors cannot be operated manually. The contactors are fitted with covers to protect them from direct contact.

Safety of installationsDamping 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 ReactorsDetuned 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.
