Direct Circuit Winding Resistance Tester HV Winding Resistance And LV Winding Resistance

The transformer DC resistance is a required test item for the factory test, installation and handover test of semi-finished products and finished products in transformer manufacturing, as well as the preventive test of power department. It can effectively find the manufacturing defects such as material selection, welding, loose connection parts, missing stocks and broken wires of transformer coils and the hidden trouble after operation.

Direct-circuit Rapit Resistance Tester can detect whether the contact of each position of the voltage tap switch is good and whether the actual position of the tap switch is consistent with the indicated position, whether there is a fracture of the lead wire, whether there is a broken strand of multi-strand wire and winding.In order to meet the needs of rapid measurement of transformer DC resistance, RSZR-01 DC Resistance Tester is developed by our company.The instrument adopts a new power supply technology, featuring small size, light weight, large output current, good repeatability, strong anti-interference ability and perfect protection function.The whole machine is controlled by high speed single chip microcomputer, high degree of automation, with automatic discharge and discharge alarm function.The instrument has high precision and easy operation, which can realize the rapid measurement of transformer resistance.

.

1). It can be used to control the instrument through special software, and the test data can be stored in a fixed format on the phone, which is convenient for data query at any time.

2). The maximum output voltage of the instrument is 24V, so it is convenient to choose a larger test current when the resistance value is high, so as to improve the test speed.

3). The instrument adopts new power supply technology, with multiple current gears and a wide measuring range. The current can be selected automatically according to the load.

4). It has a variety of protection functions such as counter potential shock, wire breaking during the test, power failure and power overheating, etc. It can reliably protect the impact of counter potential on the instrument and synchronously sound alarm.

5), with copper aluminum material arbitrary temperature conversion function, touch input arbitrary winding temperature and conversion temperature.

6), Intelligent power management technology, the instrument is always working in the state of minimum power, effective energy saving, reduce heat.

7). Seven-inch high brightness touch color liquid crystal, clear display under strong light, full touch screen operation, free switching between English and Chinese.

8). The instrument comes with a calendar clock and power off storage, which can store 1000 sets of test data and can be consulted at any time.

9). The instrument has bluetooth communication, RS232 communication and USB interface, which is used for computer communication and U disk data storage.

10). With its own panel micro printer, it can print the measurement results in English.
