Why GEYA ASVG

Three Fixes, One Chassis

Less panel, less wiring

Reactive power, 2nd–50th harmonics and phase unbalance corrected by a single unit — one point of installation, monitoring and maintenance.

A variant for every room

≤45 dB low-noise for hospitals and offices, 1U/9.5 kg for in-row racks, IP66 natural-cooling for outdoor poles — plus standard rack, wall and cabinet builds.

Priorities you control

Enable any function combination and set the priority order at commissioning; capacity allocates automatically to the duty you rank first.

Right-sized from 3 kvar

From a 3 kvar low-noise unit for a clinic panel to 150 kvar modules paralleled into cabinets — one platform covers the whole range.

ASVG Selection FAQ

Questions Engineers Actually Ask

ASVG vs installing separate SVG and AHF units — which is better?

When a bus needs both reactive and harmonic correction at comparable scale, one ASVG replaces two units — saving panel space, cabling and cost, with functions coordinated on a single DSP. Choose dedicated SVG or AHF modules only when one duty dominates heavily (say, 200 A of harmonics but little reactive demand) — then a dedicated module sizes more economically.

Which ASVG variant fits my environment?

Standard rack/wall builds suit electrical rooms. ASVG-LN (≤45 dB, built-in CT) is made for hospitals, offices and labs where noise matters; ASVG-IU (1U, 9.5 kg) slides into data-center racks; ASVG-IP66 (natural cooling) mounts outdoors on poles or walls for farm and rural distribution areas; cabinets serve centralized compensation rooms.

Can I choose which functions the ASVG performs?

Yes. Reactive compensation, harmonic filtering (2nd–50th, per-order adjustable) and unbalance correction can be enabled in any combination and re-prioritized at commissioning — the unit allocates its capacity by the priority you set, so one hardware order covers changing site needs.

One Duty Dominating the Bus?

If it's almost all harmonics — or almost all reactive power — a dedicated module sizes more economically than an all-in-one.
