Yangzhou Topu Electric Technology Co., Ltd. provides on-site voltage transformer calibrator_TP_HVPT_technical parameters

The on-site voltage transformer calibrator is developed using new testing techniques, large-scale electronic circuit design, and in compliance with relevant national regulations. It solves the problems of high workload and complicated operation in on-site verification of voltage transformers, while the product has reliable performance and powerful functions.

The high-voltage energy metering devices of power plants and substations, as well as the energy metering devices of a large number of users, are related to the interests of power generation, transmission, supply, and users. To ensure accurate measurement, it is necessary to conduct inspections in accordance with JJG1021-2007 "Power Transformers" and DL/T448-2000 "Technical Management Regulations for Electric Energy Metering Devices".

Product Features

1. Without the need for a boost source, standard transformer, or load box, the ratio and angle difference of electromagnetic voltage transformers can be tested on-site in accordance with national regulations.

2. The product has a standard voltage transformer with the same transformation ratio as the measured voltage transformer, with an accuracy of 0.02 level, which accurately measures the transformation ratio and no-load error of the measured voltage transformer. Then, based on the test results of impedance and admittance, calculate the error of the transformer

3. The equipment adopts frequency conversion technology and digital processing, with strong on-site anti-interference ability.

4. During the voltage boosting process, various protective measures should be taken to ensure personal safety and equipment safety and reliability.

5. The measurement range is wide, ranging from 6kV/100V to 220kV/√ 3V/100/√ 3V.

6. It has the functions of voltage transformer ratio, DC internal resistance, and secondary load testing of voltage transformers.

7. Intelligent judgment of external wiring status, prompting for wiring errors, variable ratios, polarity errors, etc
8. Directly issue on-site inspection conclusions, qualified or unqualified
9. Large scale storage can store up to 1000 pieces of on-site test data

10. Equipped with a printer, it can print test data on site

11. The instrument comes with a wiring diagram, which is simple and intuitive. By comparing the wiring on site, it can ensure the correct completion of testing wiring in one go, reducing preparation time.
