td6200 tester for current transformer -凯发k8国际

overview

model td6200, an apparatus to measure the ratio difference and phase displacement for current transformers in actual operation. composed of ac current source with a maximum 110 a and ac current measurement with a maximum 110 ma. it can measure and draw the curve k(i) of the ratio difference to current variety, the curve k(f) of the ratio difference to frequency variety, the curve δ(i) of the phase displacement to current variety and the curve δ(f) of the phase displacement to frequency variety.

features

● compared to the traditional detection methods of using standard transformers, adjustable resistors and capacitors, this apparatus has the advantage of high integration, simple wiring, high detection efficiency and easy traceability.

● at 50 hz / 60 hz, the ratio difference measurement accuracy is up to ±0.02 %, and the phase displacement measurement accuracy is up to ±0.01 °.

● support to measure ratio difference and phase displacement at multiple frequency points, draw frequency characteristic curves k(f), δ(f) and current characteristic curves k(i), δ(i) by software.

● strong load capability of current output, long time operation under full load and ensure value accurate and stable.

● open-circuit protection and overload protection for current test loop make a high reliability.
