FAQS on turns ratio tester

Q: What is a turns ratio tester used for?

A: A turns ratio tester measures the ratio of primary to secondary windings in transformers. It ensures transformers meet design specifications and detects faults like short circuits or insulation degradation. This tool is critical for quality control in manufacturing and maintenance.

Q: How does a transformer turns ratio tester work?

A: It applies a low-voltage AC signal to the transformer’s primary winding and measures the induced voltage in the secondary winding. The ratio is calculated by comparing these voltages. Advanced models automate calculations and display results digitally.

Q: What factors affect transformer turns ratio tester price?

A: Prices vary based on accuracy, measurement range, and features like touchscreens or data logging. Basic models start around $1,500, while high-end industrial testers can exceed $10,000. Brand reputation and certifications also influence costs.

Q: Are turns ratio testers compliant with industry standards?

A: Yes, reputable turns ratio testers adhere to standards like IEEE C57.12.90 and IEC 60076. Compliance ensures reliable measurements for power transformers. Always verify certifications before purchasing for regulatory acceptance.

Q: Can a turns ratio tester diagnose transformer health?

A: Absolutely. It identifies issues like winding deformities, incorrect tap settings, or insulation breakdown by detecting deviations from expected ratios. Regular testing helps prevent transformer failures and ensures operational safety.
