Transformers play a crucial role in power transmission and distribution systems by maintaining voltage levels for efficient energy transfer. To ensure their performance, the Turns Ratio Test is one of the most essential diagnostic tests used in transformer maintenance and quality assurance. For industries across the country, Pico Labs Ltd. offers professional Turns Ratio Test Service in Bangladesh, helping ensure your transformers operate safely, efficiently, and within specification.
The Turns Ratio Test determines the ratio between the number of turns in the primary winding and the number of turns in the secondary winding of a transformer. This ratio defines how voltage is transformed from one circuit to another. In simple terms, the turns ratio indicates how much the transformer increases or decreases voltage levels.
For example, if the primary winding has 100 turns and the secondary has 10 turns, the turns ratio is 10:1 — meaning the output voltage will be one-tenth of the input voltage.
Even slight deviations in this ratio can lead to operational inefficiencies, overheating, or potential system failure. That’s why regular testing is essential for maintaining transformer reliability.
The Turns Ratio Test is critical in ensuring that a transformer performs as per design and safety standards. It helps identify several key issues such as:
Shorted Turns: Detects if any turns in the winding are short-circuited.
Open Circuits: Identifies if there are broken or open windings.
Incorrect Connections: Confirms whether windings are correctly connected and phased.
Manufacturing Defects: Verifies that new transformers meet their design specifications.
Degradation Over Time: Helps track performance deterioration due to aging or environmental stress.
Performing regular turns ratio testing allows early detection of problems, minimizing downtime, and reducing costly repairs.
The test involves applying a low AC voltage to the primary winding of the transformer while measuring the induced voltage in the secondary winding. The test set automatically calculates the turns ratio (Np/Ns) by comparing both voltages.
A high-quality turns ratio tester provides accurate measurements quickly and safely. Any deviation from the expected ratio could indicate potential issues with winding connections, insulation, or core structure.
The Turns Ratio Test is widely used in various sectors, including:
Power Generation and Transmission Plants
Industrial Facilities
Renewable Energy Systems
Transformer Manufacturing Units
Utility Companies
In each of these sectors, the test ensures consistent voltage transformation, operational efficiency, and electrical safety.
