Zc-121a Pt excitation characteristic tester is a special instrument specially developed by our company in combination with Wuhan High Voltage Research Institute of China Electric Power Research Institute and in accordance with the latest national standard of Pt, GB / T 22071.2-2008 guide for transformer test Part 2: electromagnetic voltage transformer, and the actual needs of the transformer manufacturer 。
Zc-121a Pt excitation characteristic tester adopts the most advanced DSP + FPGA technology, with fast tracking and measurement speed, accurate data capture, powerful function and convenient use, which is at the leading level in China. The following briefly summarizes the characteristics of zc-121apt excitation characteristic tester.
Zc-121a Pt excitation characteristic tester product characteristics:
1. Fully automatic acquisition, measurement, display, storage and printing of all measurement parameters and excitation characteristic curves (voltage, current, power, frequency, equipment number, time, etc.).
2. Super large range, which can automatically and manually measure the excitation data of the set point.
3. It supports up to 100 sets of preset test sample parameters. During the test, you only need to input the number of preset test sample parameters to call up the sequence value of point * * *, which greatly improves the test efficiency.
4. The built-in super large capacity memory can store test data and upload it to PC through standard industrial communication interface (RS232). The random software developed by the company can be used to generate and edit typical test reports automatically, which is convenient for technical management and archiving.
5. The perfect protection value of over-voltage and over-current voltage is adjusted automatically according to the setting of test parameters, which is simple and can ensure the safety of the tested equipment.
6. It can also be used as volt ampere characteristic test of voltage (current) transformer and arc suppression coil.
7. Equipped with large screen graphic LCD, full Chinese menu interface, cursor prompt operation, simple and convenient; real-time display of test data and curve, automatic scaling of curve coordinates, more clear reading of the diagram.
8. Equipped with micro printer, it can print test report in real time.
Understand the characteristics of zc-121a Pt excitation characteristic tester, but you should also pay attention to the following points during operation:
1. When using the instrument, carefully read the product manual and master the correct use method.
2. Connect the wires correctly during the experiment, and then check whether the wires are correct. Power on after reliable connection
3. Among the wires of the test clamp, the thicker wires are current wires (I1, I2) and the thinner wires are voltage wires (U1, U2). The instrument adopts a special high current quick connector, which should rotate a little faster when plugging in and out.
4. Correct operation. During the test, the voltage regulator shall be slowly boosted near the test point to ensure the reliability of data acquisition.
PT excitation characteristic tester
It can be seen that zc-121a Pt excitation characteristic tester is an instrument with complete functions and strong safety properties. It's worth buying~
