Proven in the Field

Real‑world results from AltraVolt installations across India and exports — showcasing how we solve power quality challenges and deliver measurable ROI.

Case studies illustration
⚡ The Problem

Recurring CNC servo drive trips during grid sags, causing spindle encoder errors and scrapping precision components. The plant experienced 8–10 unplanned outages per month, each costing ₹2–3 lakh in lost production and rework.

🔧 The AltraVolt Solution

Installed a 75 KVA three‑phase servo stabilizer with ±0.5% regulation and <50 ms response on the main CNC line. The stabilizer includes harmonic filtering to protect sensitive servo drives.

📊 Quantified Results

↓ 85% unplanned downtime (from 9 incidents/month to 1–2 minor events).
↑ 30% tool life due to stable spindle speed and consistent surface finish.
₹ 18 Lakh annual savings in scrap and rework.

⚡ The Problem

MRI and CT scanners produced image artifacts and occasionally failed during voltage dips. The hospital also faced nuisance trips on the UPS feeding the radiology suite, affecting patient throughput and diagnostic confidence.

🔧 The AltraVolt Solution

Deployed a 100 KVA isolation transformer with electrostatic shielding and IEC 60601‑1 compliance, paired with a 50 KVA single‑phase servo stabilizer for the MRI magnet power supply. The isolation transformer reduces common‑mode noise and leakage current to <100 µA.

📊 Quantified Results

✓ Zero image artifacts since installation.
✓ UPS battery life extended by 40% (reduced cycling).
↑ 25% patient throughput in MRI suite due to fewer retakes and system resets.

⚡ The Problem

Voltage fluctuations caused uneven yarn twist and frequent thread breaks on ring‑frame machines, leading to production losses and higher waste. The mill also experienced motor overheating due to phase unbalance.

🔧 The AltraVolt Solution

Installed three 50 KVA three‑phase servo stabilizers across the spinning sections, with auto‑phase balancing and forced‑air cooling to handle the dusty environment. The stabilizers are connected in a master‑slave configuration for load sharing.

📊 Quantified Results

↓ 60% thread break incidents (from 15–20 per shift to 5–6).
↑ 12% machine utilization due to fewer stoppages.
₹ 22 Lakh annual savings in raw material and energy (cooling reduced).

⚡ The Problem

Input voltage sags (up to 30%) caused UPS battery drain and premature transfer to bypass, risking downtime for critical enterprise servers. Harmonic distortion from downstream switch‑mode supplies also increased neutral currents.

🔧 The AltraVolt Solution

Deployed two 150 KVA three‑phase servo stabilizers with ±40% input range and low output impedance, feeding the UPS inputs. Additionally, installed isolation transformers with harmonic mitigation to keep neutral‑to‑ground voltage below 1 V.

📊 Quantified Results

✓ Zero UPS transfer events in 18 months.
↓ 35% battery ageing rate (reduced cycling).
↑ 5% overall PUE improvement due to efficient power conditioning.

⚡ The Problem

Frequent tripping of escalators and elevators during peak hours, causing customer inconvenience and safety complaints. The store also experienced lighting flicker and POS system resets during voltage sags.

🔧 The AltraVolt Solution

Installed 60 KVA three‑phase servo stabilizers for the escalator and elevator power feeds, and 10 KVA single‑phase stabilizers for the POS and lighting systems. All units include overload protection and surge suppression.

📊 Quantified Results

↓ 95% escalator and elevator trip incidents.
✓ No POS downtime during voltage fluctuations.
↑ 20% customer satisfaction scores (based on surveys).
