Transformer Test Equipment

RDB- II transformer turns ratio tester overcomes the shortcomings of traditional ratio bridge test, which is easy to operate and intuitive. TTR tester adopts three-phase precision inverter power supply, and has fast test and high accuracy.

In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation and according to the preventive test regulations, it is required to test the turn ratio or voltage ratio of the running transformers, so as to check the correctness of the turn ratio of transformers, the condition of tap changer, whether the transformers are short circuited between turns, and whether the transformers can operate in parallel.

The Sweep Frequency Response Analyzer is used for power transformer with voltage grade of 6kV and above and other transformers with special purpose. The power transformer is inevitably vulnerable to impulse of various fault short-circuit current or physical collision in the process of operation and transportation and the transformer windings may lose stability under the powerful electro-dynamic force exerted by such short-circuit current, which could result in permanent deformations such as local distortion, swell or dislocation and will severely affect safe operation of the transformer.

RDZR Series Transformer DC Resistance Tester can be used for semi-finished products, finished product factory test, installation, overhaul, after changing tap changer, handover test and preventive test of power department. The DC Resistance Tester can check the welding quality of winding joint and whether there is inter turn short circuit in winding.

Transformer capacity characteristic tester includes functions such as transformer capacity, no-load loss of the transformer, load loss of the transformer and its code level determination, and electrical parameter measurement. The instrument has a high-efficiency rechargeable battery inside and can work without an external power supply.

Precision Tan Delta Test Set for HV equipment with integrated design, variable frequencies, and digital notch technology for accurate field measurements.

RD6000C Transformer Tan Delta Test Kit breaks through the traditional bridge measurement mode, adopts frequency conversion power supply technology, uses single chip computer and modern electronic technology to automatically convert frequency, analog/digital conversion, and data operation;

The DC resistance test of transformers is a must-test item for semi-finished products, finished products factory test, installation, handover test and preventive test of power department in transformer manufacturing. Dual-channel DC Resistance Tester can effectively discover whether there are manufacturing defects such as looseness, missing stocks, wire breakage, etc. in the selection, welding, and connection of the transformer coil and hidden dangers after operation.

The anti-interference pilot frequency dielectric loss tester is a high-precision instrument for testing the dielectric loss tangent and capacitance of various high-voltage power equipment in power plant, substation and other field or laboratory.

The RDZR-10A transformer DC resistance tester is a necessary test item for semi-finished product, finished product factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in transformer manufacturing.
Our Transformer dc resistance test instrument can check the welding quality of the winding joint and whether there is inter turn short circuit in the winding, whether the contact of each position of the voltage tap changer is good.
