SVGm and OPTIM SVGm static var generators and LV hybrid compensators
Country: Spain · Model: SVGm / OPTIM SVGm
SVGm static var generators of 30–100 kvar (3W) and 20–69 kvar (4W) per module and OPTIM SVGm hybrid compensators of 200–800 kvar. Response time is below 100 µs, voltage 200–480 V, frequency 50/60 Hz. They are used where the load changes quickly and phases are unbalanced, including overhead cranes, welding, elevators and data centers.

Description
SVGm modules are installed in standard rack cabinets, and up to 100 devices of different ratings are connected in parallel, with the current transformers connected only to the master. The cos φ range is from 0.7 ind. to 0.7 cap., with internal short-circuit protection and web monitoring. The SVGm-3WP-400C-480 cabinet gives 400 kvar at 400–480 V (230 kvar at 230 V) at a phase current of 580 A, with a rated short-circuit current of 40 kA and Ipk 84 kA. Dimensions are 608 × 1890 × 812 mm, weight 355 kg, version IP21/IK10 (IP41 on request), noise below 69 dBA, consumption up to 8280 W, installation altitude up to 3000 m. The interfaces are RS-485 Modbus RTU and Ethernet Modbus TCP. OPTIM SVGm adds anti-resonance 7 % stages at 189 Hz (50 Hz) or 227 Hz (60 Hz), switched by contactors under the control of the computer SMART III controller.
How to choose
First the power and the network layout are determined. The 3W module of 30–100 kvar is used for three-wire lines, and 4W of 20–69 kvar for four-wire lines with neutral. If the load is slower and space needs to be saved, the OPTIM SVGm hybrid of 200–800 kvar at 440 V or 175–625 kvar at 480 V / 60 Hz is suitable. The example OPTIM SVGm-325-480-60Hz consists of stages 3 × 75 + 100 kvar, 4 stages in total.

FAQ
What is the response time of SVGm?
Less than 100 µs. This makes it possible to compensate fast load changes of cranes, welding and elevators, as well as phase unbalance.
How many SVGm generators can be connected in parallel?
Up to 100 devices of different ratings; the current transformers are connected only to the master.
What mains voltage and frequency are permissible?
200–480 V between phases ±10 %, frequency 50/60 Hz ±5 %.
How does OPTIM SVGm differ from SVGm?
OPTIM SVGm combines SVGm with 7 % filter stages and the computer SMART III controller. The dimensions are smaller than those of a unit made only of switched stages, and the capacitive power is additionally compensated by SVGm.
