High Accuracy Transformer Turns Ratio Tester - Single & Three Phase Transformer Testing Device with LCD Display for Power Grid Maintenance & Electrical Equipment Diagnosis

Transformer Turns Ratio Tester Transformer Turns Ratio Tester Lithium battery power supply or 100-240V AC power supply is self-adaptive. It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage. Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider TTR Tester Range: 0.8～10000 Accuracy: ± (reading × 0.1%+2 words) (less than or equal to 1000) ± (reading × 0.2%+2 words) (greater than 1000 but less than or equal to 3000) ± (reading × 0.3%+2 words) (greater than 3000) Resolution Ratio: 0.9～9.9999（0.0001) / 10～99.999（0.001）/100～999.99（0.01）/1000～9999.9（0.1）/10000（1） Working power supply: AC100-240V, 50/60Hz (battery charging voltage) Handheld Transformer Ratio Group Tester 1. Variable ratio measurement range: 0.8~10000. 2. Fast measurement speed: Complete three-phase testing within 1 minute. 3. Measurement accuracy: The measurement accuracy of high-voltage side voltage is 0.05% 4. Measurement accuracy of low-voltage side voltage 0.1% 5. Ratio measurement accuracy 0.1% (0.8-3000) 6. 0.2%（3000－10000） I. Performance Characteristics 1.The three-phase CNC sine inverter power supply output has soft start and soft stop functions, so the testing speed is fast and the accuracy is high. 2.Three phase transformer, single-phase transformer, PT, CT, Z-type transformer ratio, group, polarity testing function. 3.CT ratio polarity testing function. 4.It has angle difference testing function during single-phase testing. 5.The tap changer can be tested up to 99 gears. 6.Wide testing range, up to 10000. 7.High and low voltage reverse connection reminder. 8.Output short circuit reminder. 9.Non power-off clock and date display; The data storage method is local storage, with 100 test data pieces. The stored data can be transferred to a computer (PC); 10.Thermal printer printing function. 11.Small size, light weight, convenient for carrying and use. II. Technical Indicators Range: 0.8～10000 Accuracy: ± (reading × 0.1%+2 words) (less than or equal to 1000) ± (reading × 0.2%+2 words) (greater than 1000 but less than or equal to 3000) ± (reading × 0.3%+2 words) (greater than 3000) Resolution Ratio: 0.9～9.9999（0.0001) / 10～99.999（0.001）/100～999.99（0.01）/1000～9999.9（0.1）/10000（1） Working power supply: AC100-240V, 50/60Hz (battery charging voltage)
