Transformer capacity tester transformer load tester transformer capacity and load load load load tester transformer tester I. Product Overview "power transformer", GB/T6451-1999 "three-phase oil-immersed power transformers technical parameters according to the national standard GB1094 and requirements ", RTCR-I-load transformer capacity and load characteristics tester can test voltage rating of 6,10,35 kV, capacity test range from 30 kVA to 40000kVA various models and specifications of oil-immersed transformers, dry-type transformers and capacity of special transformer load loss, load loss. When the test load loss and load loss and no external power regulator can be directly tested. For different groups of connected transformers (Y/yn0 or D/yn11) can identify the test. Even in a different transformer tap position, they do not adjust the tap, only on the instrument choice can be. RTRB-IV-load transformer capacity and load characteristics tester uses a low voltage, low current test method, enhanced security testing work. While the built-in power supply can provide greater power output, ensuring accurate test data, but also to provide a reliable signal for testing large-capacity transformer. RTRB-IV-load transformer capacity and load characteristics tester to measure in addition to the test transformer capacity, the load characteristics of the test, the test load characteristics, while still meeting the voltage, current, power, frequency, short-circuit impedance transformers and other relevant parameters. Instrument is small, light weight, simple wiring, convenient operation, accurate measurement, good stability, easy to learn, is an integral part of the electricity inspection department equipment. Second, the technical requirements of a product), Product Features:?? Large screen, high brightness, wide liquid crystal display, a screen display of all measurement data, Chinese information tips. LCD brightness, contrast can be adjusted, can be clearly displayed in strong sunlight. ?? Tester built-in mini printer, Chinese print output can be directly printed out in the field test results. ?? Within a protection circuit to avoid equipment damage and personnel accident. ?? Using long-life touch buttons, easy to operate, you can use the default settings for most operations, a key operation in the end. ?? Built-in high-energy power projects to be completed all tests in the field testing of the instrument, and do not need an external power supply regulator, up-flow and other auxiliary equipment. ?? Unique power-saving mode, to ensure the completion of various types of transformers multiple field tests. ?? Can test transformer capacity in the non-rated tap position. ?? Test data is stable and repeatable. ?? Wiring is simple, take pliers can be completed in just two tests, the test phase, regardless of gender, can optionally two phases. Two), product technical parameters: 1 Capacity Test: 30kVA ~ 500kVA range, the accuracy of 0.5, range 630kVA ~ 40000kVA, the accuracy of two two load tests: short-circuit loss (copper loss): Range 0 ~ 40000W, Accuracy 0.5 impedance voltage (Uk) and percentage (Uk%), accuracy of 0.5 3 load test: load loss (iron loss): Range 0 ~ 40000W, accuracy 0.5 load current, accurate . 0.5 4 the rest of the electrical measurement: Voltage range 0 ~ 750V, accuracy 0.2; current range of 0 ~ 50A, accuracy 0.2; Frequency Range 45 ~ 65Hz, accuracy 0.2. These measurements can be done by their own power. 5 automatic temperature compensation of test data is completed, the data will be converted to a numerical temperature rating. 6 built-in power capacity: 15AH, continuous measurement of more than 100 transformers; Output Power 600W, can be directly tested 16000KVA other large-capacity transformer. 7 The instrument provides a test signal: AC voltage 40V, maximum current 15A, standard sine wave distortion of less than 1%. 8 Transformer models (high-energy and energy-) automatically determine and print output. 9 has a memory function, can store 100 transformer information. 10. Equipped with a dedicated short-circuit test clamp for easy wiring. Optional 1000A shorting special requirements. 11. Voltage and current inputs to the chassis insulation resistance ≥ 500MΩ, working between the power input to the shell can withstand the power frequency 2KV, which lasted 1 minute AC voltage test. 12. Equipment is small (400 × 320 × 180), light weight (less than 6 kg), easy to carry. 13 Working environment: Temperature -20 ~ 50 ℃, humidity 10% to 85%.
