1. Overview

Features:

It is suitable for DC resistance measurement of various transformers, distribution transformers and inductive samples of 110kV and below;

It has a variety of measurement modes such as single-phase, three-phase Y-type phase-by-phase, three-phase Y-type simultaneous, three-phase ∆ phase-by-phase, etc., covering various application scenarios of transformer direct resistance measurement;

The whole machine is controlled by high-speed chips, with a high degree of automation and simple operation;

Using a new lithium battery power supply, the current range is multi-range, the output voltage is high, the magnetization is fast, the measurement time is saved, the maximum output current can reach 20A, the same measurement mode of 10A+10A is supported, the maximum output voltage can reach 20V, and the resistance measurement range can reach 1mΩ~20kΩ;

It has the functions of automatically judging the end of magnetization, automatically locking the resistance value and saving, without manual judgment;

It can carry out continuous measurement of transformers that need to be shifted without stopping;

It has an automatic measurement function, which can automatically select the optimal current gear according to the load;

The protection function is perfect, which can reliably protect the impact of the back EMF on the instrument;

It has the function of voice broadcasting, and the resistance value is automatically broadcast after the test is completed;

It has the function of energy recovery, which can quickly demagnetize and recover the energy of the winding, and eliminate the risk of electrification;

Backlit LCD display, clearer in sunlight;

It comes with a power-down storage function, which can store 100 sets of historical test data, which can be consulted at any time;

Equipped with Bluetooth interface, support BLE4.0 protocol Bluetooth transmission, adapt to WeChat applet;

Small size, light weight, no additional power supply, suitable for outdoor mobile operations.
