Measure and protect CT voltage and current performance, 5%and 10% error curve, various ratio, polarity, output large current for measuring CT secondary loop The fundamental structure of equipment consists of main engine, booster and power current transformer. Booster and power current transformer equipped external are optional accessories. Main engine contains full automatic booster, internal power current transformer, PC control system,320*240 lattice large screen LCD, micro printer, operation rotating mouse, PC telecommunication interface, etc. Main engine can be directly used to do CT voltage and current performance, ratio and polarity test. Voltage and current performance test maximum outputs 1000V, 20A;ratio test and secondary loop test reach to maximum 600A. features 1.Full automatic tester, only to set up number, testing maximum output voltage, maximum output current and step, equipment will boosting from zero gradually. Whole testing process is recorded automatically, and draws out voltage-current performance curve and displays automatically. 2.strong function, single can test 10% error of CT, voltage-current performance, ratio and polarity. It can be connected to computer to do test or read data by computer. 3.Large output capacity. Voltage-current performance test maximum output is to 1000V, 20A, ratio and polarity 600A. 4.External booster and power current transformer are optional. Booster boosts maximum to 2000V,20A, suitable for doing voltage-current test for 5000Kv, 1A CT. 5.LCD large screen display 6.Rotating mouse operation, cancel panel button, switch, controlling buttons, etc. 7.Large capacity memory stores 45 groups of data. Power off, data will not disappear. 8. Double operation methods, set up RS232 telecommunication interface. 9.Nontacting test, safe 10.high accuracy 11.single machine- integrated, weight 26kg, dimension 40*30*34cm, portable Input voltage Output range Measure range Measure accuracy Equip main engine 220V 0 550V, 0 20A 0 550V, 0 20A below 0.5% 380V 0 950V, 0 20A 0 950V, 0 20A below 0.5% Support external current amplifier 220V 0 1650V,0 3A 0 1650V,0 3A below 0.5% 380V 0 2000V,0 3A 0 2000V,0 3A below 0.5% External adjustor regulator 0 1000V,0 30A below 0.5% Equip main engine with current amplifier 220V 0 600A 0 600A Various ratio measure accuracy below 1% Equip working power supply AC 220V±10%,50/60Hz Working environment temperature -10°C - +50°C Measure power supply AC 220V orAC 380V Volume 300×300×400mm3
