How to Use the Voltage Transformer Frequency Multiplier AC Withstand Voltage Tester - Yangzhou Darui
Darui Electric recommends for you
TCR-100ADC Resistance Tester is a new generation of transformer DC resistance testing instrument, which can automatically select the test current according to different types of power transformers, and display the test results at a fast speed. The DC resistance tester also has functions such as storage, printing, and discharge indication. It has a built-in non-volatile memory that can store measurement data for a long time. The adoption of a liquid crystal display makes the instrument have a good human-machine interface.
Features
1. The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and simple operation.
2. It adopts high-frequency switching power supply technology, with large output current, suitable for DC resistance measurement of large and medium-sized transformers.
3. It has complete protection functions, which can reliably protect the instrument from the impact of back electromotive force, making the performance more reliable.
4. It has audible discharge alarm, clear discharge indication, reducing misoperation.
5. It has fast response speed, can directly switch the on-load tap changer in the measurement state, and the instrument automatically refreshes the data.
6. It adopts a vertical chassis structure, which is convenient for field use.
7. Intelligent power management technology makes the instrument always work in a low-power state, effectively reducing internal heating and saving energy.
8. Dot-matrix LCD, Chinese menu, print output.
How to use the DC resistance tester:
1. DC power test:
Close the main power switch, the corresponding indicator light will be on, press the "Start/Stop" key to start the test. After the test, press the "Reset" key, the instrument displays "Discharging", wait until the instrument returns to the startup interface, turn off the main power switch, the corresponding indicator light goes out, then switch the test clips for another test.
2. AC power test:
Connect the AC220V power supply, the "Charging" indicator light is on, close the main power switch, the specific operation is the same as the DC power operation.
