High-Precision LV Transformer Impedance and Voltage Test Set
General Information:
The Three-Phase Transformer Short-Circuit Impedance Tester is a specialized instrument designed for three-phase power transformers, suitable for voltage levels from 10kV to 500kV and capacity from 10kVA to 1000MVA. It adopts three-phase synchronous sampling technology, which can quickly and accurately measure the short-circuit impedance and load loss of three-phase transformers under rated current conditions. This tester is widely used in power grid commissioning, transformer maintenance, and fault diagnosis, effectively improving the efficiency and accuracy of three-phase transformer testing.
Features:
Three-Phase Synchronous Sampling: Adopts three independent high-precision sampling channels, realizing synchronous sampling of three-phase voltage and current, ensuring accurate measurement of three-phase unbalance.
Fast Test Speed: Completes a full set of three-phase tests in 30 seconds, greatly improving testing efficiency compared with traditional single-phase testing methods.
Automatic Phase Compensation: Built-in phase compensation algorithm, automatically correcting phase errors caused by wiring and instrument drift, ensuring measurement accuracy.
Multiple Wiring Modes: Supports Y, Δ, and Z wiring modes, adapting to different connection forms of three-phase transformers, with strong versatility.
Intelligent Fault Judgment: Automatically identifies wiring errors, phase loss, and other faults, and displays fault prompts on the screen, reducing operation errors.
