Product Description

Product overview:

For the power system, transformers are the core equipment in the system, so the long-term and reliable operation of transformers is related to the stability and reliability of the entire system.

At present, the DC resistance test and transformer ratio group test of distribution transformers are necessary tests for transformer power outage maintenance. To complete the above tests and operations, it is necessary to separately configure transformer DC resistance tester and transformer ratio group tester. Two types of instruments need to be carried during each test.



Product Features:

1 One time wiring, capable of completing DC resistance testing and transformer ratio testing.
2 Direct resistance testing function, for Yn type, Y type, and △ type windings, three-phase automatic testing can be used, and the three-phase imbalance rate can be calculated; The maximum output current is 20A, which can meet the testing of extremely low resistance values of low-voltage coils in distribution transformers.
3 Transformer ratio testing function, with testing functions for three-phase, single-phase, and Z-type transformers; PT/CT ratio and polarity testing functions; Blind testing function.
4 It has multiple wired and wireless communication interfaces, which facilitate the expansion of instrument functions.
5 The instrument adopts an embedded Linux operating system, which has high security, smoothness, and ease of use.
6 The instrument adopts an A7+M4 dual core architecture, which meets the real-time measurement requirements and smooth operation.
7 Industrial grade 7-inch large screen display with a fresh and minimalist display style design, creating a comfortable and convenient human-computer interaction experience for you.
8 This instrument is powered by a large capacity lithium battery and comes with a built-in
