Frequently Asked Questions

Get answers from our engineering team about voltage stabilization technology.

How do I calculate the required stabilizer capacity for my facility?
Calculate total connected load (in kW) of all equipment, multiply by 1.25 for safety margin, then convert to kVA (divide by power factor, typically 0.8). For example: 80kW load ÷ 0.8 = 100kVA stabilizer. Our engineers provide free load assessments and capacity recommendations based on your specific requirements.
What's the difference between servo stabilizers and relay-type stabilizers?
Servo stabilizers use motor-driven variable transformers for smooth, continuous voltage correction with ±1% accuracy and 20-30ms response time. Relay stabilizers use stepped switching, resulting in ±5-10% accuracy, 100-500ms response, and audible clicking. Servo technology is superior for sensitive equipment and provides longer service life.
How long does installation take and what's required?
Installation typically takes 4-8 hours depending on capacity. Requirements include: adequate ventilation space, level floor/mounting surface, input/output cabling, and proper earthing. Our certified technicians handle complete installation including testing and commissioning. We also provide training for your maintenance staff.
What maintenance is required for servo stabilizers?
Quarterly maintenance includes: cleaning carbon brushes, checking servo motor operation, tightening electrical connections, and verifying voltage accuracy. Annual service involves transformer oil testing (for oil-cooled units), bearing lubrication, and comprehensive performance testing. We offer AMC packages with scheduled preventive maintenance by our engineers.
Can stabilizers protect against power surges and lightning?
Servo stabilizers primarily regulate voltage fluctuations. For surge and lightning protection, we recommend adding surge protection devices (SPDs) at your incoming supply and stabilizer output. Our engineers can design integrated protection systems combining stabilization, surge suppression, and isolation for complete power conditioning.
