Standard On-load Voltage Divider Tester Calibration System Load Voltage Divider Tester Calibrating Fixture
Hallmarks
1) This equipment facilitates the calibration of on-load tap-changer testers, encompassing parameters such as transition resistance, transition time, and three-phase simultaneity.
2) The calibration device introduces an innovative approach by achieving "synchronous generation" of physical transition resistance and transition time. It has been calibrated by an authorized metrological verification agency, ensuring that its performance parameters meet the design requirements and are at the forefront domestically.
3) In the case of a four-pole method (eight terminals) test, the tester can be directly connected to the test port on the test bench.
4) In the case of a two-pole method (four terminals) test, the IAUA terminal of the tester should be connected together with the A terminal, the IBUB terminal should be connected together with the B terminal, and the ICUC terminal should be connected together with the C terminal.
Outline
An on-load voltage divider tester calibration device is used to calibrate and verify the accuracy of an on-load voltage divider tester. On-load voltage divider testers are used to measure the ratio of voltage divisions in an electrical circuit and are commonly used in areas such as power systems and power metering.
