Transformer Tester

---

Our company's innovatively developed large-capacity lithium battery-powered transformer comprehensive test system only requires one set of equipment to complete two projects: transformer DC resistance test and transformer ratio group test, without the need to frequently remove and connect test wires.

The whole machine is controlled by high-speed single chip microcomputer, with a high degree of automation, automatic discharge, and discharge alarm function. It has high precision and easy operation, which can realize the rapid measurement of the direct resistance of the transformer.

This instrument is a new generation of rapid tester integrating three-phase testing (Yn, Y, △) and demagnetization functions. It is an ideal device for measuring the DC resistance of large power transformers. 

The DC resistance test of a transformer is a mandatory procedure for power utilities, carried out during the manufacturing process for both semi-finished and finished products, as well as during factoryacceptance,installation, commissioning, and preventive maintenance testing. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as potential hazards existing after operation. 

This instrument is a new-generation rapid tester that integrates three-phase testing (Yn, Y, △) with demagnetization functions. It is designed for accurate and efficient measurement of DC resistance in large power transformers. The unit features a large, high-resolution LCD screen for convenient on-site operation, along with intuitive menu prompts for simple use. All resistance test items can be completed with a single connection. 

This tester is meant for three-phase transformers, particularly suitable for Z-winding transformers, rectifier transformers, and electrical systems railway Scott, inverse Scott balanced transformers. Input single phase power, and generate three or two phases of power by Internal power module, output to high voltage side, and then sample high voltage and low voltage at the same time, finally, the group, variation ratio, error, and phase difference are calculated.

This tester is a dedicated instrument for measuring the capacity of distribution power transformers, as well as the no-load and short-circuit losses of transformers. 

Low-voltage short-circuit impedance measurement is a fundamental item in routine test projects. By comparing the short-circuit impedance values measured before and after the transformer is impacted by short-circuit current, the degree of winding deformation can be preliminarily estimated based on the magnitude of the change.

The on-load tap changer is the only moving component directly connected to a transformer circuit, making its detection increasingly important. 

This instrument is designed specifically for testing on-load tap changers. It measures transition waveforms, transition times, transition resistance values at each stage, and the three-phase synchronism of transformer tap changers.

Capacitance And Dissipation Factor Tester is a high-precision instrument designed for on-site measurement of dielectric loss tangent and capacitance in various high-voltage electrical equipment. It is widely used in power plants, substations, laboratories, and other testing environments.

The tester based on the measurement of the windings characteristic parameters inside the transformer, and using the world's developed countries 'sound internal fault frequency response analysis (FRA) method, able to make an accurate internal transformer fault judgment.

The transformer winding deformation tester measures the characteristic parameters of the transformer's internal windings and uses the internal fault frequency response analysis (FRA) method and impedance analysis method currently being developed and improved by advanced countries in the world to make accurate judgments on the transformer's internal faults.
