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
