1. Light beam oscilloscope function
The instrument has three channels that can simultaneously record phases A, B, and C. It can automatically capture and display the transition process of transition resistance and time jumps during the transition. It is not affected by weather and is far superior to light beam oscilloscopes.
2. Strong comprehensive capability
Within one instrument, it can measure various parameters of the on-load tap changer, such as whether there are breakpoints during the selection and switching process, transition waveforms, transition time, transition resistance, and three-phase synchronization. With the function keys,
it can analyze the time and resistance values of each time segment in the waveform.
3. Print output
The instrument is equipped with a panel-mounted high-speed printer with front paper loading.
4. Good anti-interference performance
The all-aluminum alloy chassis and the instrument are equipped with power supply noise filters and anti-interference circuits, allowing reliable measurement on-site even with poor power quality and strong electromagnetic field interference.
5. Data retention and data communication
The data and waveforms measured by the user can be saved in the instrument. Up to 128 groups of waveforms can be stored and will not be lost due to power failure. The test results stored on-site can be transferred to a computer via a dedicated data cable through the serial port for storage
(our company provides dedicated software).
NRIKC-8000 Transformer On-load Tap Changer Tester is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of on-load tap changers in power transformers and special transformers in power systems. It uses computer control and specially designed measurement circuits to measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of the on-load tap changer. Users can measure directly from the tap changer leads or directly from the transformer three-phase bushings and neutral point according to needs and site conditions. The instrument has functions for analyzing, storing, and printing the measured data. It solves the problems of outdated measurement methods and lack of dedicated testing means for on-load tap changers in power transformers. It can promptly diagnose potential faults in on-load tap changers during preventive tests of power equipment and transformer overhauls, which is of great significance for improving the reliability of power system operation.
