XW-3312A Transformer DC Resistance Tester (10A)

1. Overview:

Winding DC resistance measurement is one of the routine tests of a transformer, which is used to check the connection and mechanical properties between the winding and the lead, and whether the resistance between each phase winding is balanced to ensure the safe operation of the transformer.

The transformer DC resistance tester with a 32ARM kernel, which is the core of the process, can control the whole machine, perform self-calibration and steady-flow judgment, data processing, display, and other functions, and can manage all kinds of DC resistance measurements of transformers and mutual inductors. Greatly convenient for field staff.
