I.Transformer Winding Coil Resistance Tester Introductio
The DC resistance is thetransformer’s semi-finished product, finished product test, installation,commissioning test, and electric part prevention test necessary testproject,the transformer coil can
effectively find the device welding,connecting parts loose, missing unit, disconnection, and other manufacturingdefault and other hidden danger occurred
after
operation.
The DC Resistance transformerto meet fast measurement requirement, we developed RCZL-20A DCResistance Tester. The instrument is a new powerful technology, smallsize, light weight, high output current and other characteristics.
The device is controlled bythe microcontroller, with a high degree of automation, automatic dischargefunctions. It is a test instrument of high precision,
simple, directway to achieve fast transformer measurement.
