Our company has innovatively developed the 3-in-1 distribution transformer testing system (including DC resistance + transformation ratio + insulation resistance) powered by a large-capacity lithium battery. With just one set of equipment, we can complete the three different test items, without the need for frequent disassembly and rewiring of test lines.
Main Functions And Features
1、With wiring one time, it’s capable of conducting DC resistance tests, transformation ratio tests, and intelligent tests.
2、DC resistance test function. Yn, Y, and △ type windings can all adopt the three-phase automatic testing method, and calculate the three-phase imbalance rate. The maximum output current is 20A, which can meet the test requirements for the extremely low resistance values of the low-voltage windings of distribution transformers.
3、 Transformation ratio test function. It has functions for three-phase, single-phase, and Z-type transformer tests; PT/CT transformation ratio and polarity testing functions; blind testing function.
4、 Insulation resistance testing function, with a maximum output short-circuit current of 5mA and adjustable from 1mA to 5mA. It also has insulation resistance IR, absorption ratio DAR, and polarization index PI testing capabilities.
5、 It has various wired and wireless communication interfaces, which can facilitate the expansion of the instrument's functions.
6、The instrument adopts an embedded Linux operating system, featuring high security, smoothness, and ease of use.
7、 The instrument adopts an A7 + M4 dual-core architecture, which not only ensures real-time measurement but also ensures smooth operation.
8、 The industrial-grade 7-inch large-screen features a fresh and simple design. It combines full touch control with a one-click shuttle operation, creating comfortable and convenient human-computer interaction experience.
8、 This instrument is powered by a large-capacity lithium battery and comes with a built-in charger.
