RDTBT Series Transformer Comprehensive Test Bench

Product Description

The RDTBT series transformer test bench is designed to test the performance of power transformers and distribution transformers. It can perform different tests, including no-load tests, load tests, frequency doubling induction tests, and power frequency withstand voltage tests.

The test bench uses a high-performance microcomputer control system to collect and process test data accurately. During no-load, short-circuit, and other transformer tests, the system can complete data sampling and calculation automatically, reducing errors caused by manual measurements and calculations with separate instruments.

With a digital display and simple operation, the RDTBT series transformer test bench allows users to view test results quickly and clearly. It provides an efficient and reliable solution for transformer manufacturers, testing laboratories, and power companies to check transformer quality and performance.

These functions help ensure stable and safe operation during transformer testing.

What Tests Can RDTBT Transformer Test Bench Perform?

Transformer performance depends on several electrical parameters. The RDTBT series provides multiple testing functions to help engineers obtain complete transformer data.

No-Load Test

The no-load test measures transformer core performance when the secondary winding is open. It helps evaluate:

• No-load loss

• No-load current

• Core quality

• Magnetic performance

Accurate no-load test results help manufacturers control transformer efficiency and reduce energy losses.

Load Loss and Short-Circuit Test

The load test evaluates transformer winding performance under rated load conditions.

The system measures:

• Load loss

• Impedance voltage

• Power factor

• Short-circuit parameters

These measurements are important for checking winding resistance, manufacturing quality, and transformer operating characteristics.

DC Resistance Test

DC resistance measurement helps identify:

• Winding connection problems

• Poor electrical contacts

• Abnormal resistance between phases

The test results can support transformer quality inspection and help prevent failures caused by winding defects.

Transformer Ratio and Vector Group Test

The transformation ratio test verifies whether the transformer voltage ratio meets design requirements.

It can help check:

• Turns ratio accuracy

• Phase relationship

• Winding connection condition

This test is essential before transformer installation and commissioning.
