三阶段便携式仪测试

The YC98C is a portable standard to verify active and reactive three phase meters (3 or 4 wires) and single phase meters. It is designed to work in the field to check the parameters of power line and test the meter. Features With 4.7 inch 480 272 dot TFT color screenWide voltage supply range: 45V 480VWide current testing range: CCT test 500:1 dynamic rangeConnection with current clamp: standard 100A. From 5A to 2000A current as option.Two ways for power supply: external AC power supply or test lead power supply Functions Measuring mode: gives information about the parameters of the line under test, like: Phase voltage, current, angle Active power, reactive power, apparent power. Phase and three-phase power factor. Phase angle of phase to phase voltage Phase angle of phase to phase current Frequency.Vector diagram: draw the line vector diagramWaveform: show the wave form of voltage and currentHarmonics: make a graphic and numeric analysis of the THD. (2nd 51st)Meters test: Performs the test to the meters. The data field configurable in this function is the serial number, the meter type, the constant, the divisor factor (for HF), the type of test and cycles.CT ratio test: get CT ratio by synchronously testing primary and secondary current of CTWiring check: judge the wiring right or wrong automaticallyEnergy accumulating: accumulate active and reactive energy in a setting time, used for meter's dial testClamp CT self-calibration: check whether the clamp CT is accurate and re-calibration.Test data storage: can store 1000 data groups. Data include meter type, serial number, constant, error, date, etcDownload the testing program: can download 1000pcs testing planning to the equipment, convenient for local useIt has a RS232 interface to communication with a PC Technical Specification Accuracy 0.3% (active), 0.5%(reactive) Test voltage input 30V-480V Test current input 5A, 100A, 500A, 1000A, 2000A (current clamp) Phase measurement 0°-360° Frequency measurement 45Hz-65Hz Harmonic measurement 2nd -51st Power supply45V-480V Power consumption <5W Dimension(W×H×D) 190mm×140mm×50mm Weight1kg
