According to Prevent Test Regulations of State Grid, the operating transformers should be tested for turn ratio and voltage ratio regularly in the production of semi-finished products and finished power transformers and before operation of newly installed transformers. The traditional transformer turn ratio bridges have many weaknesses such as complex operation, indirect readings, and inevitable conversion because that the tested result is the value of single-phase turn ratio. FA8631 transformer turns ratio tester overcomes the defects of the traditional transformer ratio bridges, applying a large liquid crystal display with high resolution, Lithium cells to supply power and Chinese menu to
2.1 AC-DC Dual-use: Lithium battery powered or 220V AC charger powered self-adaptively.
2.2 A full-scale battery could continuously test 100 transformers turns ratio groups.
2.3 With intelligent charging management, this transformer could display remaining power and alarm low battery indicator, also backlight could adjust automatically, which can save power.
2.4 High speed and high accuracy because the total output is three-phase sine inverter, output voltage could adjust automatically, and soft start or soft stop function is equipped.
2.5 Include three-phase transformer, single-phase transformer, PT, Z-shaped transformer turn ratio, group and polarity checking test function.
2.6 Blind test function, which is testing transformers turns ratio or group without knowing high or low voltage connection methods.
2.7 CT transformer turn ratio polarity checking test function.
2.8 Angle differences test included in single-phase test.
2.9 The maximum testable position of tap position is 197.
2.10 The widest test range up to 10000.
2.11 High and low voltage reverse connection protection function.
2.12 Output short-circuit protection function.
2.13 Clock and date display without power consumption; data storage methods consist of native storage and USB flash disk storage. Native storage could store 500 data which can be transfer and restore in USB flash disk; the data of USB flash disk is Word format, which can be edited and printed on the computer.
2.14 The function of thermal printer, fast and noiseless.
2.15 It is convenient to carry because of small size and light weight.
3.1 Range: 0.9～10000
