Voltage Correction
At PurityElec, we provide advanced Voltage Correction solutions that ensure your electrical systems receive the optimal, stable voltage they need for peak performance.
Fluctuations in voltage — whether overvoltage or undervoltage — can damage sensitive equipment, reduce efficiency, and cause costly downtime.
What is Voltage Correction?
Voltage Correction is the process of monitoring and adjusting the voltage level supplied to your electrical network so that it remains within the ideal operating range for all connected equipment.
Our solutions use state-of-the-art technology to stabilize voltage in real-time, protecting your assets and improving system reliability.
Why is Voltage Correction Important?
Voltage fluctuations can cause:
• Equipment Damage – Motors, drives, and electronics can overheat or fail prematurely.
• Production Downtime – Sudden voltage dips can cause process interruptions.
• Energy Losses – Unstable voltage leads to inefficiency and higher power consumption.
• Reduced Lifespan – Electrical components wear out faster when exposed to poor voltage quality.
Our Voltage Correction Technology
We use Automatic Voltage Regulators (AVRs), Static VAR Compensators (SVCs), and advanced electronic control systems to deliver:
• Precise Voltage Stabilization – Maintain ideal voltage at all times.
• Fast Response Time – Instant adjustment to sudden load or supply changes.
• Harmonic Immunity – No interference with power quality.
• Scalable Solutions – Suitable for small facilities to large industrial plants.

Frequently Asked Questions
-
Q1. What is voltage correction?
-
Q2. Why is voltage correction important?Because under-voltage or over-voltage can cause:
- • Motor overheating or failure
- • Malfunction of sensitive electronics
- • High energy losses and reduced efficiency
- • Tripping of circuit breakers or UPS systems
- • Reduced equipment lifespan
-
Q3. Who requires voltage correction solutions?Industries, data centers, hospitals, commercial complexes, and residential buildings facing frequent voltage fluctuations, unbalanced loads, or poor power quality.
-
Q4. What causes voltage fluctuations?
- • Overloaded transformers or feeders
- • Long transmission/distribution lines
- • Unbalanced loads across phases
- • Harmonics and poor power factor
- • Sudden switching of heavy equipment
-
Q5. What are the common problems due to poor voltage regulation?
- • Flickering lights
- • Equipment damage (motors, compressors, IT hardware)
- • Nuisance tripping of protection devices
- • Increased downtime and maintenance costs
-
Q6. How is voltage correction achieved?
- • Automatic Voltage Regulators (AVR)
- • On-load Tap Changer (OLTC) transformers
- • Reactive Power Generators (RPG) for dynamic reactive power compensation
- • Servo stabilizers for precise regulation
- • Capacitor banks or Static VAR Compensators (SVC)
-
Q7. What is the difference between a stabilizer and a voltage regulator?
- • Stabilizer: Maintains constant output voltage by adjusting taps or servo motors, mostly for small/medium loads.
- • Regulator (AVR): Electronic or transformer-based device providing continuous automatic regulation for industrial and large-scale loads.
-
Q8. Can voltage correction improve power factor?Yes, devices like RPG and SVC not only correct voltage but also improve power factor by providing reactive power support.
-
Q9. What are the standard voltage limits?As per IEC 60038 and utility standards, voltage variations should generally be within ±6% to ±10% of the nominal rated voltage.
-
Q10. How to know if my system needs voltage correction?If you notice:
- • Frequent equipment failures or overheating
- • Repeated voltage complaints from meters/monitoring
- • Power quality analyzer reports showing deviation beyond permissible limits
- • Unstable operations in sensitive equipment (UPS, medical devices, IT servers)
-
Q11. What are the benefits of voltage correction?
- • Stable and reliable power supply
- • Extended equipment life
- • Reduced downtime and failures
- • Improved energy efficiency
- • Compliance with power quality standards
-
Q12. Is voltage correction cost-effective?Yes. The investment in regulators, stabilizers, or RPGs typically pays back quickly by reducing equipment failures, avoiding downtime, and saving energy.
