Product Feature And Application
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.
9 .This instrument is powered by a large-capacity lithium battery and comes with a built-in charger.
