Clean, Quiet, Always-On Power for Healthcare
MRI and CT systems inject harmonics while demanding rock-steady voltage, in an uptime-critical, low-noise environment. GEYA AHF and the low-noise ASVG-LN clean the waveform and hold voltage quietly enough for clinical areas.
Power Quality in a Hospital
Healthcare facilities stress the grid in three specific ways. We measure each before recommending hardware.
Harmonics from MRI / CT Imaging
Imaging systems and their drives inject pulsed harmonic currents that distort the waveform and can disturb other sensitive medical equipment.
Fix · AHFStrict Voltage Stability for Diagnostics
Diagnostic and life-support equipment needs voltage held within a tight band; sags or swings can corrupt imaging or interrupt critical care.
Fix · SVG / AVCUptime-Critical, Low-Noise Environment
Power-quality gear in or near clinical areas must run continuously and quietly - standard cabinets are often too loud for wards and imaging suites.
Fix · Silent ASVG-LN
Clean Waveform, Whisper-Quiet
Imaging systems inject harmonics while demanding steady voltage. A GY-AHF cancels MRI / CT harmonics, a GY-SVG holds voltage and power factor, and the low-noise GY-ASVG-LN - down to 45 dB - does reactive, harmonic and imbalance compensation quietly enough for clinical areas. A GY-AVC keeps terminal voltage steady through dips for life-critical loads.
- GY-AHF cancels 2nd-50th harmonics from imaging systems
- GY-SVG holds PF ≥0.99, response <10 ms for stable diagnostics
- GY-ASVG-LN: all-in-one compensation at just 45 dB
- Wi-Fi / RS485 monitoring for uptime-critical facilities
What We Deploy in Healthcare
A quick map from each hospital power-quality problem to the GEYA product that solves it.
| Power Quality Problem | Recommended Product | Voltage Range | Key Spec |
|---|---|---|---|
| Imaging (MRI / CT) harmonics | AHF · GY-AHF Series | 220V – 800V | 2nd–50th, ≥95% |
| Voltage stability for diagnostics | SVG · GY-SVG | 220V – 800V | <10 ms, PF ≥0.99 |
| Low-noise / clinical-area compensation | Silent · GY-ASVG-LN | 220/380V | Noise 45 dB |
| Voltage dips on critical loads | AVC · GY-AVC | 220/380V, 30–400kVA | ±20%, stepless |
DSP digital control (SVG: TI TMS320F28335; AHF / ASVG: TI TMS320F28377), 50/60 Hz, single- or three-phase (3-/4-wire), parallel-capable, two- & three-level. Device voltage 220–800 V; 10/35 kV via high-side sampling. Module ratings: SVG 5–150 kvar, ASVG 3–150 kvar, AHF 15–200 A, AVC 30–400 kVA.
Sensitive-Load Projects
Representative GEYA deployments on UPS-backed and harmonic-sensitive loads, with measured before/after results.
AHF for UPS Output Voltage Distortion
Sensitive equipment harmonics pushed UPS output voltage THD to 17%, risking shutdown. A high-performance AHF cut it to about 3% on all three phases, keeping critical loads online.
AHF for Precision-Cooling Harmonics
Variable-frequency precision-cooling compressors injected harmonics into the power room. A high-performance AHF cut current THD from 60% to 5% and lifted power factor from 0.84 to 0.96.
Healthcare - Common Questions
Engineer-to-engineer answers to help you spec the right device for a medical facility.
How do I clean MRI / CT harmonics without adding noise?
Use the low-noise GY-ASVG-LN - it does reactive, harmonic (2nd-50th) and imbalance compensation in one cabinet at just 45 dB, quiet enough to sit near imaging suites, with a built-in grid-side sampling CT for easy installation.
Will an AHF or SVG keep diagnostic voltage stable?
Both help. A GY-AHF AHF cleans the harmonics that distort UPS and equipment voltage (a GEYA project cut UPS output THD from 17% to about 3%), while a GY-SVG holds voltage and power factor with a response under 10 ms; a GY-AVC adds series voltage regulation through dips.
Is there a silent unit for clinical areas?
Yes - the GY-ASVG-LN is purpose-built for noise-sensitive environments at 45 dB. For uptime-critical sites it pairs with Wi-Fi / RS485 monitoring so facilities teams can watch power quality 24/7.
