NR6800 series transformer on-load tap changer tester
is used to measure and analyze the electrical performance indicators of power transformers and special transformers on-load tap-changers in power systems. It can realize the measurement of the parameters such as the transition time, transition waveform, transition resistance, and three-phase consistency of the on-load tap changer. During the action of the on-load tap changer, the waveform is generated in real time to facilitate the analysis of the measured data, and it is equipped with functions such as storage and printing to realize the scientific management of the test data.
◆ Three-phase independent constant current source, can quickly establish test current;
◆ It has perfect waveform display and analysis functions and can automatically calculate the transition time and transition resistance;
◆ Large-screen LCD display, full Chinese menu operation;
◆ Built-in printer, can print measurement results and waveforms.
◆ Sampling rate: 10~20kHZ
◆ Transition resistance measurement range: Y/0 type transformer 1~40Ω; Y type transformer 1~20Ω
◆ Measurement accuracy: 1~5Ω, 10%; 5~40Ω, 5%
◆ Time and synchronization accuracy: 1%
◆ Dimensions: 410mm*320mm*200mm
◆ Weight: 6kg
