We need to know what transformer is turns ratio before we begin reading the text. Transformer turns ratio refers to the ratio of the number of turns on one side of the transformer to the number of turns on the other side. It plays a very important role in the design and operation of transformers.

Two different devices of the measure of transformer turns ratio.

The one is transformer turns ratio meter. It usually be used to measure the transformation ratio of a transformer. And it will directly display the transformation ratio value of the transformer. This function is very convenient for us to know the result. Its function is mainly focused on measuring the transformation ratio of the transformer and providing numerical results. And its use is also very simple. There are the main steps of its use.

The first step: Ensure that the transformer turns ratio meter is in good condition and properly calibrated. And then we must keep the transformer to be tested is de-energized and disconnected from any power source. It is crucial to keep the transformer away the power.

The second step: Connect the transformer turns ratio meter to the transformer windings following the manufacturer’s instructions.

The third step: Set the transformer turns ratio meter to the appropriate test mode for transformer turns ratio measurement.

The fourth step: Initiate the measurement using the transformer turns ratio meter when the connections and settings are properly configured. Typically, the transformer turns ratio meter will display the turns ratio of the transformer directly on its screen.

The fifth step: Analyze the measurement results to ensure they fall within acceptable tolerances for the specific transformer type and application.

After completing the measurement, remember to disconnect the transformer turns ratio meter from the transformer and keep all connections are safely disconnected. If you forget to do this step, your transformer turns ratio meter may be hurt.

The other instrument is transformer turns ratio tester. It has other functions than the transformer turns ratio meter. Except measuring the transformation ratio of a transformer. It can also measure the winding resistance, winding inductance, ground insulation resistance, etc. of the transformer. But its price is higher than transformer turns ratio tester. As we all know it is impossible that more versatile machines are cheaper. At the same time, its operation is more complex, and it require the operators command more knowledge. Because operators may need to make additional settings or adjustments to meet the specific needs of the test.

Why we need turns ratio test in transformer?

The transformer turns ratio can affect the voltage conversion efficiency, power transmission efficiency and operating stability of the transformer.

When designing a transformer, it is necessary to select an appropriate turns ratio. The selection of turns ratio is based on circuit requirements and load characteristics. It can ensure that the transformer can achieve voltage conversion and power transmission stably and reliably during operation. At the same time, the choice of transformer turns ratio will also affect the size, weight and cost of the transformer.

Therefore, it is crucial to conduct the turns ratio test in transformer for us.
