Dry type transformer material analysis tester

In the current production of distribution transformers, using aluminum wire instead of copper wire as the conductor material has become a public practice in the industry. The main reason for this situation is that aluminum wire transformers can save costs compared to copper wire transformers and have strong economic efficiency. Transformers are static electrical equipment made based on the principle of electromagnetic induction. They have the functions of transforming voltage, current, and impedance, and are widely used in various fields of engineering. What are the consequences of using aluminum wire instead of copper wire in transformers? Higher power consumption and poor power quality!

thisTransformer material analyzerIntegrating transformer material testing, capacity testing, characteristic testing, direct resistance testing, and transformation ratio testing, this is a high-precision instrument specially developed by our company to address this issue. It can easily detect whether dry-type transformers are using aluminum instead of copper as a substitute, accurately test transformer capacity, and accurately detect whether users have changed or replaced transformer nameplates. It can also accurately measure power frequency parameters such as capacity, load loss, no-load loss, impedance voltage, and no-load current of various transformers.

This instrument not only has the characteristics of small size, light weight, high measurement accuracy, and good stability, but also adopts a large screen LCD display window, graphical menu operation, and Chinese character prompts. It has a display interface that integrates multiple parameters on one screen, a friendly human-machine dialogue interface, easy operation, and easy learning, greatly improving work efficiency. It is popular among power users and quality supervision departments at all levels.

Dry type transformer material analysis tester

Features

Can accurately determine the material of 10KV dry-type distribution transformers.

Can blind measure the capacity of 10KV distribution transformers and 35KV, 110KV, and 220KV transformers.

It can measure the load loss, no-load loss, short-circuit voltage, no-load current, etc. of various types of transformers.

It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non rated voltage), and current correction (short-circuit test under non rated current conditions). The operator only needs to input the correction index according to the transformer type, and the instrument can automatically calculate the corrected result. It is very suitable for units that do not have slightly larger capacity transformer short-circuit test conditions.

Allow external voltage transformers and current transformers for extended range measurement, capable of measuring any parameter of the test sample.

The tester adopts a 7.0-inch, 800 * 480 graphic dot matrix industrial grade color LCD screen with high brightness, wide temperature, wide viewing angle, and clear visibility under sunlight.

The full Chinese character menu and graphical operation prompts enable friendly human-machine dialogue, and touch buttons make operation easier, suitable for all seasons of winter and summer.

Users can print out the results of the test data at any time through a micro printer.
