Product parameters:
The Transformer LV Short-Circuit Impedance Tester does not require an external voltage regulator and uses a primary connection method. Upon entering the parameters, it initiates three-phase testing and automatically calculates the impedance error percentage, providing clear and intuitive results. This fast-testing device is designed for on-site detection of transformer winding deformations.It is a quick test instrument to check whether the transformer has winding deformation

സവിശേഷത:
1. The tester is powered by AC220V low voltage, automatically supplying current to the AB, BC, and CA high-voltage windings of the transformer. It collects data simultaneously and calculates the impedance error percentage automatically, providing intuitive testing results.
2. The tester performs three-phase testing automatically using the primary connection method, rather than the inverse connection with the testing wires.
3. The tester supports both single-phase and three-phase testing, with options for manual or automatic operation.
4. The tester adjusts the output current to match the test item’s impedance limits.
5. The test item can be measured without the need for an external voltage regulator.
6. The tester includes functionality for measuring zero-sequence impedance.
7. It also supports inductance measurements.
8. The tester features a large LCD display with a Chinese menu, simplifying operation with on-screen notes and guidance.
9. The tester offers printing and storage capabilities, with high testing accuracy, advanced automation, compact size, and lightweight design.
