Description Overview GAOTek impedance test equipment tester is a high precision instrument developed by our company for measuring transformer no-load, load and zero sequence impedance parameters. It can accurately measure a series of parameters such as no-load current, no-load loss, short-circuit loss, impedance voltage, harmonic content and distortion rate of various transformers. Features This tester can measure no-load current, no-load loss, impedance voltage, load loss, zero sequence impedance for all kinds of transformer Can adjust waveform distortion, temperature (offer two simple methods that adjust temperature and adjust additional loss) Can measure three-phase voltage, three-phase current, average voltage, average current, two-phase active power (only display A, C power due to adopt two-phase method), total power Can measure 2 to 42 times harmonic wave content of each phase voltage and current Total distortion rate of each signal (harmonic wave distortion) Can display the real-time waveform of each voltage and current The distortion of waveform visually Technical specification Input characteristicInput characteristics Voltage measured range：0 V to 750 V Width limited Current measured range：5 A to 100 A internal range switching automatically Input Voltage：±0.2% Current：±0.2％ range owner：±0.5%（Cos > 0.1），±1.0%（0.05 < Cos < 0.1） Temperature 14 °F to 104 °F (-10 ℃ to 40 ℃) Charging power AC 160 V to 265 V Insulation the insulation resistance between voltage, current input terminal and the chassis ≥100 MΩ Between power supply input terminal and the shell can withstand 2 kV (rms) for 1 minute Host volume 12.5 in x 9.44 in x 5.11 in (32 mm x 24 mm x 13 mm) Weight 6.6 lb (3 kg)
