Product Introduction
The application of the EHDGQ-T type high-voltage three-phase composite transformer calibration standard device and its testing methods has changed the current traditional single-phase testing methods. It complies with the requirements of the current national and industry standards (test guidelines) and is easy to implement. It eliminates the need for multiple wiring tests in the current single-phase methods, saving a significant amount of labor and materials, enhancing work efficiency, and eliminating additional errors brought by single-phase testing. It also allows for accurate error testing of three-phase voltage transformers with Y\YO connections, ensuring accurate and reliable measurement. The new device's calibration method for three-phase composite transformers (metering boxes) will promote the design and improvement of product manufacturing quality. It can more accurately reflect the characteristics of composite transformers in working conditions and more reveal potential issues during actual operation, thereby ensuring fair and just electricity measurement.
Product Features
Revamped the existing conventional single-phase testing method, in compliance with current national and industry standards (test guidelines), and is easy to implement. It eliminates the need for multiple wiring tests in the current single-phase method, saving substantial labor and resources, enhancing work efficiency, and reducing additional errors associated with single-phase testing. It also allows for accurate error testing of three-phase voltage transformers with Y\YO wiring, ensuring precise and reliable measurement. The new equipment's testing method for three-phase composite transformers (metering boxes) will promote the design and improvement of manufacturing quality for composite transformer products. It can more accurately reflect the characteristics of composite transformers in operation and identify potential issues during actual work, thereby ensuring fair and just electricity measurement.
