FAQs of Turns Ratio Meter:

Q: How do I operate the turns ratio meter in manual and auto modes?

A: This turns ratio meter supports both manual and automatic modes. For manual mode, you manually initiate each test using the control interface. In auto mode, the device automatically sequences through a pre-set testing process, making it ideal for repetitive measurements in laboratory or industrial environments.

Q: What is the 4-terminal Kelvin Connection, and why is it important?

A: The 4-terminal Kelvin Connection is used for precise measurement by minimizing errors due to lead and contact resistance. This configuration ensures high accuracy (0.2%) when testing transformer turns ratios, especially critical for low-resistance windings.

Q: When should the turns ratio meter be calibrated, and is a calibration certificate included?

A: Each meter is factory calibrated to ensure optimal accuracy, and a calibration certificate is provided with every unit. Recalibration is recommended as per your organizations quality protocols, or if the device is exposed to extreme conditions or mishandling.

Q: Where is this meter best utilized, and who are its main users?

A: This meter is primarily designed for use in electrical laboratories and industrial facilities to test transformer turns ratios and winding polarity. It is ideal for distributors, exporters, manufacturers, suppliers, and traders within the electrical equipment sector across India.

Q: What is the proper storage condition for the turns ratio meter?

A: The meter should be stored in a dry environment with humidity below 70% RH, at temperatures between 0C and 50C, to maintain accuracy and prolong operational life.

Q: How does the meter ensure user and transformer protection during tests?

A: The device is engineered with built-in overload, short circuit, and fuse protection systems, meeting IS-2026 safety standards. These features safeguard both the operator and the transformer under test from potential electrical hazards.

Q: What are the benefits of using this turns ratio meter compared to traditional models?

A: This digital LCD model offers superior accuracy, clear real-time readings, robust data output options (RS232/USB), shock and corrosion-resistant construction, and enhanced safety featuresmaking it a comprehensive and reliable choice for transformer analysis.
