10A DC Resistance Tester
For Digital Automatic Transformer Winding Resistance Testing
Product Description
XHZ1010 10A Transformer DC winding resistance tester
Transformer DC resistance is a must-test item in transformer manufacturing for semi-finished products, finished products, factory test, installation, overhaul, after changing the tap changer, handover test and preventive test in the power sector. You can check the welding quality of the winding joints and whether the windings have short-circuits between turns. You can check whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap changer matches the indicated position, and whether the lead wire is broken. Whether there is stock breakage, etc. In order to meet the needs of rapid measurement of transformer DC resistance, the XHZ1010 transformer DC resistance tester developed by our company. The instrument adopts a brand-new power supply technology, which has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and perfect protection functions.
The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation, with automatic discharge and discharge alarm functions. The transformer winding dc resistance tester has high test accuracy and easy operation, which can realize rapid measurement of transformer direct resistance.
Functional characteristics
1. The instrument can be fully controlled through dedicated software using a mobile phone, and the test data is stored in a fixed format on the phone, making it easy to query data at any time.
2. The maximum output voltage of the instrument is 24V, which facilitates the selection of a larger test current for high resistance values and improves the testing speed.
3. The instrument adopts a new power supply technology, with multiple current ranges and a wide measurement range. It can automatically select the current according to the load and is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
4. It has multiple protection functions such as back electromotive force impact, wire breakage and power outage during testing, power overheating, etc. It can reliably protect the impact of back electromotive force on the instrument and synchronously sound an alarm.
5. With any temperature conversion function made of copper and aluminum materials, touch to input any winding temperature and conversion temperature.
6. Intelligent power management technology ensures that the instrument operates at the minimum power state, effectively saving energy and reducing heat generation.
7. Seven inch high brightness touch color LCD, clear display under strong light, full touch screen operation, and free switching between Chinese and English.
8. The instrument comes with a perpetual calendar clock and power down storage, which can store 1000 sets of test data and can be viewed at any time.
9. The instrument has Bluetooth communication, RS232 communication, and USB interface for computer communication and USB data storage.
10. Equipped with a panel mounted micro printer, it can print measurement results in English.
