Power Transformer Three Channel DC Resistance Tester ,Three Phase 10A Test Current Output

I. Products Description and Application

Transformer DC resistance test is one of the most important test item in the finished product and semi-finished product factory test, installation and hand-over test in the transformer manufacturing and in the preventive test of the electric power sector it can effectively find manufacturing defects such as looseness, strand lack and broken line in the material selection, welding and connection part of the transformer coils and the hidden danger existing after running.

In order to meet the demand for quick measurement of transformer DC resistance. Our company has developed a new generation of DC resistance tester by making use of own technical advantages, . Using the brand new third-generation power supply technology, it has small volume, light weight and large output current, etc.

Model FK-20A DC resistance tester is with a new power technology, small size, light weight, large output current(max.10A three phas and single phas 20A). It is controlled by a single-chip, high automation with automatic discharge function and discharge instructions. It is with high precision and can achieve a rapid measurement for the transformer direct resistance.The equipment has high accuracy and easy operation, it can realize quick measurement DC resistance of Power transformer .

II. Features

1. The current output of the equipment is large; it can choose current automatically to make the operation easy and simple;
2. Three-channel measurement, real-time acquisition, simultaneous measurement of three resistance-values, and calculate three-phase resistance unbalance;
3. It can do both simultaneous measurements of three-phase and measurement by traditional single-channel. And it is easy to use along with the temperature conversion function
4. With perfect protection circuit to ensure high reliability;
5. With no power-down calendar, clock, and 80 sets of data storage, retrieval, and printing function;
6. It can set print information such as the phase sequence of resistance, the tap location and so on;
7. Vertical chassis structure facilitates an on-site operation;
8. With a sound alarm, and its discharge instruction is clear to reduce the misuse.
