equipment used platform interface technology, large-screen LCD display, full English prompts automatic measurement, the entire instrument operation simple; apparatus small size, easy to carry, only a small number of people who would quickly complete the measurement of work;
,10%.in the company's integration of up-flow, step-up device with the purchase of equipment, it can be used to protect the current transformer volt-ampere characteristics and 10% of the error curve test. ,10%; Easy operation, and can automatically display the volt-ampere characteristic curve, and draw 10% of the error curve;
;instrument voltage transformer can be qualitative measurements: measurement, instrument voltage transformer primary side voltage plus a certain frequency, we can measure the time of the induction voltage and secondary voltage, obtained voltage transformer in the voltage difference and angular than poor;
;instrument measures both current and voltage transformer secondary site load, measure the load current transformer ratio of difference and angular deviation;
,,e instrument can measure does not identify the current transformer or voltage transformer turns ratio, and the measurement of accurate and quick, stable and good performance, without an additional source of up-flow or step-up; 120%,,,;The instrument can measure the current transformer 5% ~ 120% at any point between the difference and angular than the poor do not need the standard current transformer and external l converter, measurement accuracy to meet the technical requirements for field test use;
