Power Transformer Single Channel DC Resistance Tester , 5A Test Current Output , Automatic Test
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-5A DC resistance tester is with a new power technology, small size, light weight, applied to DC resistance measurement to middle-sized and small-sized transformer and PT.
II. Features
- It is controlled by high-speed MCU, with high automation and easy operation;
- With a new power technology, the equipment has many current gears and wide measuring range. It can automatically select current according to the load
- Applied to DC resistance measurement of middle-sized and small-sized transformer and PT;
- It has comprehensive protection function with reliable protection against the impact from the counter potential to the instrument to ensure more reliable performance;
- It is with a sound alarm, and its discharge instruction is clear to reduce the misuse.
- Fast response makes it directly converse the on-load tap during measurement and automatically refresh the data.
- By an intelligent power management technology, the equipment is always working in the minimum power state to effectively reduce the internal heating and save energy.
