电功率分析

电能质量指供给用电设备的电力的稳定度与一致性。它涵盖电压、频率、波形特性等多项指标，保障电气设备高效、稳定运行。优质的电能意味着供电无断电、无电压波动、无波形畸变；反之，上述电力问题会造成设备故障、运行效率下降，甚至设备损毁。

电能质量分析仪（PQA）是评估、维护电能质量的核心设备，其重要性体现在以下方面：

1. 排查电力异常问题

电能质量分析仪可捕捉各类电能扰动，包括电压暂降、电压暂升、瞬态冲击、谐波等，这类扰动都会对设备运行造成不良影响。

2. 避免设备损坏

通过持续监测电能质量，能够防止劣质供电环境损毁精密电子设备，延长设备使用寿命。

3. 提升能源利用效率

对电能质量开展分析，可定位电力系统内的能耗损耗与低效环节，便于针对性整改，提升整体能效。

4. 满足法规标准要求

众多行业强制要求符合指定电能质量规范。借助电能质量分析仪可验证供电系统达标，规避罚款与处罚风险。

5. 提升系统运行稳定性

稳定优质的电能是工业产线、数据中心、医疗机构及其他关键基础设施可靠运行的基础。电能质量分析仪可保障这类设施稳定、高效运转。

Dewesoft电能质量分析仪可依据 IEC 61000-4-30 A 级标准测量各类关键电能质量指标。与市面上其他电能质量仪表不同，Dewesoft电能质量分析仪可实现更精细化的电能质量分析，支持原始数据存储、故障特性分析、谐波分析，还能额外计算多种电气参数与机械参数。更重要的是，Dewesoft 功率分析系统不仅限于电压与电流测量，还提供全同步多物理场测试能力，包括：NVH（振动噪声），温度（接触式 + 红外），GNSS / CAN / 视频和多物理量同步采集。
