What is the current transformer calibrator
Transformer
The current transformer calibrator is used for high-voltage electric energy measurement in power generation and substations. It uses detection technology and large-scale electronic design. It solves the problems of high intensity and complicated actual operation on the current transformer and voltage transformer calibration site.
Principle of current transformer calibrator
The new design concept of virtual instrument is used for the transformer calibrator. You only need to operate the virtual instrument interface on the computer side and enter the required parameters such as transformer type, range, capacity, power factor, etc., to complete the configuration and start of the automatic test of current transformers and voltage transformers, analyze and calculate the test results and manage the database , And print out various types of records and certificates according to customer requirements. This equipment is ideal equipment for power systems and other companies engaged in transformer verification.
Advantages of current transformer calibrator
- It has the functions of recursive method to measure current transformer deviation and potential difference method to measure voltage transformer deviation, which is conducive to on-site metrological verification of metrological verification equipment.
- There is no need for standard current transformers, current risers, load boxes, voltage regulating control boxes and large current wires. The verification of current transformers is achieved by simple test wiring and operation, which reduces the work intensity and improves at the same time. Improve work efficiency and facilitate on-site verification of transformers.
- The internal standard voltage transformer with the same transformation ratio as the measured current transformer, with an accuracy of 0.05, can accurately measure the transformation ratio and no-load deviation of the measured current transformer. Then the test results of impedance and admittance are integrated to calculate the deviation of the transformer.
- Detect with different frequency power supply models close to frequency I to prevent on-site electromagnetic radiation and power frequency series influence.
- The measurement coverage is wide, which can reach 5a/5a~25000a/5a or 25a/1a~5000a/1a.
- It has the function of changing the ratio of the current transformer and detecting the internal resistance of the secondary winding.
- Choose 640480 high-resolution display LCD, the interface is humanized, and the operation is designed. Touch operation makes the operation more convenient and faster.
- The application of precise software optimization algorithm further improves the accuracy of measurement data information.
- Intelligent detection and judgment of external connection line conditions, prompting wiring errors, transformation ratio, etc.
- Able to automatically combine test data to judge out-of-tolerance. The out-of-tolerance data is displayed through the anti-black display, so that the data characteristics of the transformer are clear at a glance.
- Verification results can be presented on the spot, qualified or unqualified.
- The large-capacity memory can store up to 1000 on-site data tests.
- Connect the printer to print test data on site.
- The automobile chassis of the injection mold of the engineering project should be shock-resistant and compressive to ensure the safety of the actual operation staff and machinery and equipment on the spot measurement and verification.
