Elevate safety and reliability with our Capacitance Tan Delta Testing Kits. Automated, high precision, and suitable for challenging environments. Capacitance Tan Delta Testing Kits all have good reviews and feedbacks.

The Sweep Frequency Response Analyzer evaluates transformers (6kV and above) for faults and accidents. Actively test transformer deformation to prevent power system accidents.

The test transformer windings is a crucial testing tool used for various purposes in transformer manufacturing. It serves as a necessary test item for semi-finished products, finished products in factory testing, installation, overhaul, tap changer replacement, handover tests, and preventive tests conducted by power departments.

The RDZR-340Y 3 phase DC Resistance Tester is a cutting-edge solution for transformer manufacturing, offering simultaneous three-phase testing, rapid measurement, and comprehensive analysis to detect coil defects and operational risks. Its unique features include independent current/voltage sampling and real-time display of resistance and unbalance rates, significantly reducing test times for large power transformers.

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.

Transformer Load and No-Load Tester for precise measurement of low voltage short-circuit impedance in 35kV+ transformers, featuring advanced microcomputer technology, portable design, and efficiency enhancement.

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.
