Automatic Transformer Test System/Automatic Parts Analyzer Model 3250/3252/3302

Chroma 3250/3252/3302 transformer test system, for a transformer production or QC incoming and outgoing inspection, with high stability and high reliability of the precision measurement instruments. 3250/3252 provide 20Hz-200kHz test frequency, 3302 provides 20Hz-1MHz test frequency. The transformer scanning test program covers all kinds of transformer low-voltage measurement parameters. Including inductance, leakage inductance, turn ratio, DC resistance, impedance, coil-to-coil capacity and other primary parameters; quality factor, series equivalent resistance and other secondary parameters, as well as short-circuit inspection. High-speed digital sampling technology and scanning test fixture (A132501) design, so that the previous time-consuming and inefficient transformer production inspection becomes accurate and fast.

The 3250/3252/3302 also provide a variety of output impedance modes for selection, making it possible to solve the problem of inductance difference caused by the difference in test current between test instruments due to the difference in test output impedance. In addition, the inductance conversion method is provided in the turn ratio measurement technique, which can improve the turn ratio measurement error caused by high leakage ratio of low coupling coefficient transformers.

In addition to the transformer scanning function, the 3252/3302 also provides the LCR Meter function, which can be applied to various parts for incoming and outgoing inspection, R&D analysis or production line automation applications.
