Circutor OPTIM SVGm-600-440 Hybrid Var Compensator

A 600 kvar, six-step hybrid compensator for large industrial incomers

The Circutor OPTIM SVGm-600-440 (code RG20F9) is the 600 kvar model of the OPTIM SVGm hybrid range, giving 510 kvar at a 400 V supply and 600 kvar at the 440 V reinforcement voltage. Five contactor-operated 100 kvar filter steps plus the 100 kvar static var generator make six steps in total.

The cabinet is 1254 mm wide, 1959 mm high and 804 mm deep and weighs 642 kg, so it is a major floor-standing item with its own foundation and cable entry planning. Like the other models it uses rejection filters tuned to 189 Hz (p = 7 percent), is controlled by a computer SMART III regulator, and protects each step with HRP NH-00 fuses.

OPTIM SVGm-600-440 functions

• 600 kvar at 440 V; 510 kvar at 400 V
• Composition 5 x 100 kvar + 100 kvar; six steps
• SVGm static var generator covers the fast-moving part of the demand
• Detuned filter steps at 189 Hz (7 percent) for networks carrying harmonics
• Capacitive compensation for sites with self-supply PV
• Every step fused with NH-00 high-rupture-capacity fuses
• Cabinet standard IEC 61439-2; conditional short-circuit current 40 kA

Neighbouring sizes

When 600 kvar is the right size

Choose the RG20F9 when the plant demand at 400 V is of the order of 500 kvar, which is what this unit delivers (510 kvar), and when part of the load is fast. The next sizes in the range are the 500 kvar model (428 kvar at 400 V, five steps) and the 700 kvar model (592 kvar at 400 V, seven steps). The voltage of 440 V is the reinforcement voltage; the use voltage is 400 V. Send the maximum demand, power factor target and harmonic data so we can check the size.

Installation notes

At 642 kg the cabinet needs a rated floor, lifting equipment and a plan for the access route into the electrical room. Printed conditions are IP20, -10 to +45 C working temperature, humidity to 95 percent without condensation and altitude to 2000 m. Noise is below 63 dBA. CTs of 5/5 A to 9000/5 A can feed the regulator, and the earthing system is TN or TT.

Where the OPTIM SVGm-600-440 is used

It suits large incomers in factories, process plants and commercial complexes that have both harmonic content and fast reactive power swings, and plants adding solar. Because the maximum working temperature is 45 C, the room must be cooled in summer; the heat from filter reactors is an additional load that the room design should include.

Selection and installation notes

This cabinet is a heavy floor-standing assembly of several hundred kilograms. Plan the foundation or floor loading, the lifting and transport route into the electrical room, the incomer cable and busbar entry, the clearance around the cabinet for ventilation and the room temperature before ordering. The network data that matter are the supply voltage, the short-circuit level, the harmonic spectrum and the required target power factor. A power quality measurement before ordering helps to confirm the rating, and the commissioning should include setting the regulator targets and recording the harmonic levels.
