    China, Wuhan GuoDian HuaRui Power Test Technology Co.,Ltd.
    whose preexistence is GuoDian Wuhan High-voltage Testing Research Institute, has combined the essence of institutional reform and science & technology industry with the progress and development of high-voltage technology.Is approved by the ministry of commerce of China has right of import and export trade and business development and producers.
    As a producer and researcher having its own independent intellectual property rights, it is the domestic professional producer of transmission and transformation measuring and testing equipments of big current & high voltage in complete set. Also, it is the earliest institute who has researched and developed the technology of high voltage testers, which is applied by our competitors in manufacturing productions through technical transformation. In aspects of producing domestic testing and special transformers and its varieties, it is also one of the largest, the strongest and the most outstanding manufactures in production capacity and technology strength. Domestically, there are no companies preceding us in technically developing high-tech products and we are endowed with successful experience and accumulation of the sophisticated technologies. Situated in the high-and-new technology development zone of WuHan East-lake, it has foundered and registered as a joint-stock hi-tech company comprehensively covering doing research, design, manufacturing, sales and service support and applies the modernized and collectivize management system.

Type Deformation of Power Transformer Winding Characteristic Tester
        This type of instrument is adopted by introduction of foreign technology and the latest nondestructive examination equipment of the power transformer internal fault. It is used for confirming the degree of the deformation of transformer internal winding which is the important method of the preventative nondestructive examination. It applies to the power transformer of 6.3kV-500kV. The whole operating function will be pointed out in Chinese or simple English on the screen of the microcomputer. It is made up of a portable computer, a color printer and the main measurement system. The instrument can be divided into two types of testing methods by frequency response and short-circuit impedance.

Range of frequency point: 1-5 kHz 1-100 kHZ 1-500kH 500-1MHz (The special layout)
Precision: Wandering of frequency point Δfni≤2‰fni (The average value in the frequency domain)
Amplitude resolution: 0.001dB
Irregularity degree of the passband≤0.05dB ((The average value in the frequency domain)
Weight: 20kg
Experience accumulation: 200 main transformers
