AC/DC power supply transformer ratio group tester

Instrument Introduction
According to the requirements of the preventive testing regulations for electric power, it is necessary to regularly conduct turns ratio or voltage ratio tests on transformers, including semi-finished and finished products during the production process, transformers before being put into operation, and transformers during the operation of the power system. The traditional variable ratio bridge is cumbersome to operate, the readings are not intuitive, necessary conversions are required, and the test results only reflect one phase ratio.
Yangzhou Topu Electric Technology Co., Ltd. launchedAC/DC power supply transformer ratio group testerOvercoming the shortcomings of traditional variable ratio bridge testing, it completes three-phase variable ratio testing in one go, with fast testing speed, high accuracy, and improved on-site testing efficiency. The instrument adopts two power supply methods, AC and DC, and can be used with or without mains power on the test site, which is very convenient.

safety measures
1. Before using this instrument, be sure to carefully read this user manual.
2. The operator of the instrument should have general knowledge of using electrical equipment or instruments.
3. This instrument can be used both indoors and outdoors, but should be avoided from rain, corrosive gases, excessive dust, and high temperature environments.
4. Instruments should avoid severe vibrations.
5. The maintenance and adjustment of instruments should be carried out by professionals.
6. The yellow, green, and red colors of the test clamp correspond to the A, B, and C phases of the transformer, please wire them correctly.
7. High and low voltage cables cannot be connected in reverse.
8. When testing single-phase transformers, only use yellow and green wire clamps, and the red wire clamp should be suspended.
