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 전원 공급 장치는 3상 입력, 3상 출력이며 중간에 DC가 있습니다. 7개 채널, 입력 테스트용 3개 채널, 출력 테스트용 3개 채널, DC 테스트용 1개 채널 및 AIT 고전류를 갖춘 전력 분석기로 테스트해야 합니다. 고정밀 전류 센서 시리즈는 DC를 테스트할 수 있을 뿐만 아니라 또한 현재 테스트에 가장 이상적인 선택인 높은 정밀도로 AC를 테스트합니다.
