EPTTR-D is three phase, automatically test set specially designed for turns ratio, group test, PT and CT polarity measurements of power, distribution and instrument transformer. Features:It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage.based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is widerWide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000.It has perfect protection functions such as reverse connection protection and output short circuit protection.5.6-inch super industrial high-brightness color LCD screen, still visible under strong sunlight.equipped with printer, facilitate data printingIt can be stored locally and on USB memory.Specifications:Range0.9~10000Accuracy±(Reading×0.1%+2 words)(≤500)±(Reading×0.2%+2 words)(>500≤3000)±(Reading×0.3%+2 words)(>3000)Resolution ration0.9~9.9999(0.0001)10~99.999(0.001)100~999.99(0.01)1000~9999.9(0.1)10000 and above(1)Working power supplyAC220V±10%, 50/60Hz Instrument weight3.8 kgInstrument dimension325 mm(L)×225 mm(W)×125 mm(H)Use of temperature-10ºC~50ºCRelative humidity≤90%,No dewMore details on Transformer Turn Ratio Tester EPTTR series please contact EPHipot Electric, we have professional tech team to design correctly designed products and systems.
