Characteristics
◆ The transformer tester integrates test wiring display, data acquisition, analysis processing, measurement control, storage, printing, and protection into one unit. The entire test process is fully automatic, with outstanding advantages of high efficiency and high precision. ◆ The transformer tester has a backlit LCD display, showing 18 parameters such as three-phase voltage and current simultaneously; digital meters replace pointer meters, and all test data is displayed in real-time (locked) on the screen, avoiding errors caused by parallax, conversion, calculation, and other factors during the test. This makes the test accuracy higher. In particular, it completely solves the difficulty of operators reading multiple meters at the same time and recording multiple sets of data simultaneously, ensuring accurate and reliable test data. ◆ Data processing uses automatic storage and microcomputer printing, with beautiful, standardized, neat, and clear data tables. All test data is filled into the corresponding tables in real-time, avoiding manual transcription and recording processes, ensuring the authenticity and reliability of the data. Users can also set the printing format as needed. ◆ It has the advantages of small size, light weight, high precision, and simple testing, making it an ideal product for the power sector to upgrade.

The transformer comprehensive tester consists of three major parts: 1. Computer and data processing software system; 2. Data collection system for each test unit; 3. High-voltage control and instrument monitoring comprehensive system; Introduction to the transformer comprehensive tester software: 1. The software installation conditions can work normally under Windows 98, Windows 2000, Windows XP, etc.; 2. Basic functions of the software: ① The transformer comprehensive test bench software can operate and control the transformer ratio tester, transformer winding DC resistance tester, and transformer characteristic tester; ② The transformer comprehensive test bench software can query by test number, capacity, and test date; 3. Specific requirements for the transformer comprehensive test bench software: ① The software human-machine
Safety measures interface is friendly, and operation is intuitive and simple; ② The software can automatically receive downloaded data or manually enter data. System configuration: (1) Transformer comprehensive test bench; (2) Voltage/current transformer control cabinet (optional); (3) Power control cabinet (optional); (4) System auxiliary cabinet (optional); (5) Transformer no-load/load characteristic tester (power analyzer); (6) Transformer DC resistance tester; (7) Transformer ratio and group tester; (8) High-voltage test transformer; (9) Medium-frequency generator set; (10) Induction voltage regulator; (11) Temperature patrol instrument; (12) Temperature sensor; (13) Partial discharge detection system (optional); (14) PLC controller; (15) Industrial computer and dedicated software; (16) Video surveillance system.
1. Before using this instrument, you must read this manual carefully. 2. The operator of the instrument should have general electrical knowledge. 3. The instrument should be used in places avoiding rain, corrosive gases, excessive dust, high temperature, direct sunlight, etc. 4. The instrument should avoid severe vibration. 5. After the test, be sure to wait until the discharge alarm sound stops before turning off the power and removing the test leads. 6. When measuring no-load tap-changing transformers, be sure to wait until the discharge indicator alarm sound stops before switching gears. 7. During the test, it is forbidden to move the test clips and power supply lines.
Precautions
1. For no-load tap-changing windings, it is not allowed to switch the no-load tap changer during the test or before the discharge is complete. 2. For inductive test objects, it is not allowed to remove the test leads before the discharge is complete (when the buzzer is sounding) to avoid electric shock. 3. If the external AC220V suddenly loses power during the test, the instrument will start automatic discharge. At this time, it is not allowed to remove the test leads immediately; you can only remove them after 5 minutes.
