Project Description
Product Features:
Test Y0, Y, △ transformer, the resistance value is directly displayed without conversion
The data analysis is humanized, which can automatically find out the faults in the waveform and mark them
The display of the waveform is to automatically adjust the resistance value and the amplitude of the time according to the sampled data
The △-type transformer can show the same period of time
Can be tested with or without winding
The four-terminal wiring method provides high-precision resistance measurement without wire compensation
Continuous testing can be done in the middle of the test, saving the time of transformer power outage
LTKC transformer on-load tap changer tester This instrument is designed according to the high voltage test equipment of the power industry standard of the People’s Republic of China, and is designed in general technical conditions DL/T846 and 8-2004, which can meet the requirements of the “Power Equipment Handover and Preventive Test Regulations” , It is required to check the action sequence of the on-load tap-changer and measure the switching time and other requirements.It also belongs to circuit breaker finder tool.
It can realize the precise measurement of the on-load tap-changer’s transition time, transition waveform, transition resistance, three-phase consistency and other parameters. It is an ideal equipment for testing on-load tap-changers. (The user is an on-load switch that adjusts the capacity, please inform in advance)
Product nicknames: on-load tap-changer tester, transformer on-load tap-changer tester, transformer on-load switch tester.
Four-terminal wiring method provides high-precision resistance measurement without wire compensation
Continuous testing can be done in the middle of the test, saving the time of transformer power outage The instrument can survive word report, which is convenient for data management and query
The instrument is controlled by a small computer, with an external 800×480 color LCD touch screen, a high-speed printer, and an external mouse, which is easy to operate
The instrument can automatically save 1000 sets of data, or it can be saved with an external USB flash drive.
