电能质量分析仪

电能质量(Power Quality)，从普遍意义上讲是指优质供电，包括电压质量、电流质量、供电质量和用电质量。导致用电设备故障或不能正常工作的电压、电流或频率的偏差，其内容包括频率偏差、电压偏差、电压波动与闪变、三相不平衡、暂时或瞬态过电压、波形畸变（谐波）、电压暂降、中断、暂升以及供电连续性等。 在现代电力系统中，电压暂降和中断已成为最重要的电能质量问题。电能质量分析仪 ，是对电网运行质量进行检测及分析的专用便携式产品。可以提供电力运行中的谐波分析及功率品质分析，能够对电网运行进行长时间的数据采集监测。同时配备电能质量数据分析软件，对上传至计算机的测量数据进行各种分析。为向客户提供权威公正准确的电能质量分析仪的第三方检测数据，特开展此检测项目。

Power Quality, in a general sense, refers to high-quality power supply, including voltage quality, current quality, power supply quality and power consumption quality. Deviations in voltage, current or frequency that cause power consumption equipment to malfunction or fail to operate properly include frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase unbalance, temporary or transient overvoltage, waveform distortion (harmonics), voltage sag, interruption, voltage swell, and power supply continuity, etc. In modern power systems, voltage sag and interruption have become the most critical power quality issues. Power Quality Analyzer is a dedicated portable device for detecting and analyzing the operating quality of power grids. It can provide harmonic analysis and power quality analysis during power operation, and can perform long-term data collection and monitoring of power grid operation. It is also equipped with power quality data analysis software to conduct various analyses on the measurement data uploaded to the computer. This testing project is specially launched to provide customers with authoritative, impartial and accurate third-party testing data for power quality analyzers.
