FAQ

Frequently Asked Questions

Get answers from our engineering team about voltage stabilization.

How do I calculate the required stabilizer capacity?
Calculate total connected load (in kW), multiply by 1.25 for safety margin, then convert to kVA (divide by power factor, typically 0.8). Example: 80kW ÷ 0.8 = 100kVA stabilizer. Call us for free load assessment.
What's the difference between servo and relay stabilizers?
Servo stabilizers use motor-driven variable transformers for smooth voltage correction (±1% accuracy, 20-30ms response). Relay stabilizers use stepped switching (±5-10% accuracy, slower response). Servo is superior for sensitive equipment.
What maintenance is required?
Quarterly: Clean carbon brushes, check servo motor. Annual: Transformer oil testing (oil-cooled units), bearing lubrication. We offer AMC packages with scheduled maintenance by our engineers.
