1. Application
FUOOTECH FTDC-5A digital DC resistance tester uses advanced switching power supply and precision measurement technology, with high-speed microcontroller as the core, high-speed A / D converter and program-controlled current source technology to achieve unprecedented measurement effect and highly automated measurement function.
It has the characteristics of high precision, wide measurement range, stable data, good repeatability, strong anti-interference ability, perfect protection function, fast charge and discharge speed and so on. The instrument is small in size, light in weight, and easy to carry. It is a new generation product for measuring DC resistance of inductive equipment such as transformers, motors, and transformers. It is an ideal product for measuring the DC resistance of transformers in power generation / power supply units, transformer manufacturing industry, and large and medium-sized power consumption enterprises.
2. What is DC winding resistance used for?
The winding resistance test is used to find open windings, shorts to ground, wrong turn count, wrong wire gauge, resistive connections, round wires in hand that are not connected in a coil, some connection mistakes, the resistance balance between phases, and in some cases shorted turns.
Winding resistance is an important measurement because other tests and measurements will not find some of the problems a resistance measurement will find. Some of these are the wire gauge issues, resistive connections, and blown or disconnected magnet wires in hand.
