The load of the UPS is mostly nonlinear, and the UPS itself absorbs energy from the grid, and the load of the grid is also nonlinear. Since the current waveform of the nonlinear load is severely distorted, the peak-to-peak ratio and total harmonic distortion of the waveform are important technical indicators that UPS must examine. For the measurement of nonlinear loads with severely distorted waveforms, it is difficult for ordinary electrical instruments to measure accurately. AIT high-current series high-precision current sensors equipped with high-precision power analyzers can accurately measure non-sine waves, and can continuously, quickly and accurately measure harmonics. analyze.
• UPS の電源は三相入力、三相出力で、途中に DC があります。入力テスト用に 3 チャンネル、出力テスト用に 3 チャンネル、DC テスト用に 1 チャンネル、および AIT 高電流の 7 チャンネルを備えたパワー アナライザでテストする必要があります。このシリーズの高精度電流センサーは、DC をテストするだけでなく、また、AC を高精度でテストできるため、電流テストに最適です。
