Transformer Ratio Bridge Tester Manufacturer Safety Measures
1. Be sure to read this manual carefully before using this instrument.
2. The operator of the instrument should have general knowledge of electrical equipment or instruments.
3. This instrument can be used indoors and outdoors, but should avoid rain, corrosive gases, excessive dust, high temperature, direct sunlight and other places.
4. The instrument should avoid severe vibration.
5. Maintenance, care and adjustment of the instrument should be carried out by professionals.
6. The yellow, green and red test clips correspond to phases A, B and C of the transformer respectively, do not connect them incorrectly.
7. Do not connect the high and low voltage cables in reverse.
8. When testing a single-phase transformer, only use the yellow and green clips, do not use them incorrectly, and the unused test clips should be left suspended.
Transformer Ratio Bridge Tester Manufacturer Product Applications
Designed with modern electronic technology, the instrument operation is controlled by a microcontroller. Its large LCD screen can intuitively display three-phase ratio, error, tap position and other information. The instrument is designed with a longitudinal test function for tap windings, which can automatically determine the tap position and store the corresponding ratio values. This instrument is suitable for ratio testing of transformers with various connection groups, including Z-type.
Product Features
1. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. Built-in power supply, automatically generates three-phase high-power test power.
3. Can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. Can automatically perform waveform distortion correction, temperature correction, voltage correction, and current correction (short-circuit test under non-rated current conditions). The operator only needs to input the correction index according to the transformer type, and the instrument will automatically calculate the corrected result. This is very suitable for units that do not have conditions for short-circuit testing of slightly larger capacity transformers.
5. Wide voltage range: the maximum voltage can be measured up to 750V, and accuracy can be guaranteed without switching gears. It will not damage the instrument due to incorrect voltage gear selection.
6. Battery remaining percentage indication function, not just a simple low battery alarm.
6. Large screen, bright LCD display, full Chinese menu and operation prompts to achieve friendly human-machine dialogue, touch buttons make operation easier, wide temperature LCD with brightness adjustment, can adapt to winter and summer seasons.
7. Users can print out the test data at any time through the micro printer.
8. Test result storage function, can store 200 sets of capacity test data.
