Audited Supplier Kg-iii Transformer Ratio Group Tester Current Transformation Turn Ratio Testing Machine ISO9001
Product Introduction
According to IEC and relevant national standards, transformer ratio test is a must-do item in the process of power transformer production, user handover and maintenance test. This can effectively supervise the quality of transformer products in the factory and use process, prevent short-circuit, open circuit, connection error, internal failure or contact failure of transformer regulator.
The KG-III multi-functional desktop automatic ratio tester independently developed and produced by Wuhan Kegang Power Electric Co., LTD has the advantages of simple operation and complete functions in addition to being completely according to the on-site requirements of users. The characteristics of stable and reliable data are also a fully automatic ratio tester in China so far that can carry out blind testing (without knowing any nameplate parameters of the transformer under test, the variable ratio and group number can be accurately measured, and the phase Angle can be accurately measured).
The KG-III automatic transformer ratio group tester can adapt to the needs of various large and small transformers ratio testing (including Z-type transformer, rectification transformer, electric furnace transformer, non-integral shift phase transformation, equilibrium transformer, Scott and reverse Scott transformer), is so far in the domestic ratio test technology advanced, perfect test items, comprehensive measurement parameters of the ratio tester.
The KG-III automatic transformer ratio group tester adopts the engineering plastic shell independently designed and manufactured by our company, which is beautiful and practical in appearance. Field testing is easy to operate

Product Characteristics
1, real three-phase test: single-phase power input, internal digital synthesis of three-phase standard sine wave signal source, through the high-fidelity power amplifier, produce three-phase test power supply (distortion less than 0.1%, symmetry better than 0.05%) output, test results have better equivalence, there will be no group misjudgment and other phenomena.
2, powerful function: both single-phase measurement, but also can realize the automatic test of three-phase winding, single-phase, three-phase can measure polarity, phase Angle, a complete measurement of AB, BC, CA three-phase variable ratio, phase Angle value, error, tap position, tap value and other parameters, can automatically identify the group number.
3. Phase Angle measurement function: accurately measure the phase Angle between the high and low voltage sides, and can measure the ratio and Angle of the transformer for non-integral points.
4, hexagonal diagram display function: the test results are displayed in digital and hexagonal vector diagram, which can visually see the transformer connection group.
5, blind test function: no need to choose the wiring mode, no need to choose the wiring group, measurement Y/△, △/Y transformer without external shorting, can automatically switch the wiring mode according to the selected test content. It is completely possible to measure the ratio and group number of a transformer without a nameplate.
6, tap-changer test: can quickly measure the ratio and ratio error at each tap-changer position, rated ratio only need to be entered once, do not have to enter repeatedly to calculate the ratio error at each tap-changer position.
7, at the same time with the number of turns ratio measurement and operating voltage ratio measurement of two functions, the operating ratio can more truly reflect the transformer in the actual operation of the case, the actual value of the voltage ratio.
8. Good vibration resistance: enhances the vibration resistance.
9, using 5.6 inch HD true color LCD screen, display data effect and vector image effect intuitive and delicate.
10, the test source used in this instrument is a standard sine digital source of digital synthesis, the distortion is less than 0.1%, not affected by the quality of the working power supply.
11, easy to carry: small size, light weight.
12, built-in high-capacity lithium-ion rechargeable battery, on-site without any power to complete the test work, a full can be continuous more than 800 measurements.
