Description
Overview
GAOTek portable xDSL testers is process of user handover and maintenance test that the transformer test must be done, so it can be used for quality supervision of transformer, to prevent the transformer inter-turn short circuit, open circuit, connection error, voltage regulating switch internal fault or contact failure. We develop the production of automatic ratio testers according to the user’s requirements on-site using, make the operation more convenient, complete functions, reliable data, test speed is greatly improved. To meet the needs of all kinds of small medium and large transformer test.
