•电容器组开关的双级功率因数•用于减载的低频率/需求输出，从而节省电力成本•用于PLC接口的kWh、kvarh和kVAh脉冲输出•用于累计电量的脉冲输入，例如kWh、kvar h、kVAh、，功率分析选项非线性负载（如变速驱动器、计算机和电子镇流器）可能会产生不必要的谐波，从而导致断路器跳闸、电话干扰以及变压器、电容器或电机过热。对于故障诊断，如检测过小的中性线、评估谐波额定变压器的需求或判断谐波滤波器的有效性，谐波频谱的详细信息是有用的，可通过功率分析选项获得。电压和电流波形可通过EnerVista PQM设置或第三方软件在PC上捕获和显示。SCR开关的畸变峰值或缺口为采取纠正措施提供了线索。• dual level power factor for capacitor bank switching • underfrequency/demand output for load shedding resulting in power cost savings • kWh, kvarh and kVAh pulse output for PLC interface • Pulse input for totalizing quantities such as kWh, kvarh, kVAh, etc.e) Power Analysis Option Non-linear loads (such as variable speed drives, computers, and electronic ballasts) can cause unwanted harmonics that may lead to nuisance breaker tripping, telephone interference, and transformer, capacitor or motor overheating. For fault diagnostics such as detecting undersized neutral wiring, assessing the need for harmonic rated transformers, or judging the effectiveness of harmonic filters, details of the harmonic spectrum are useful and available with the power analysis option.Voltage and current waveforms can be captured and displayed on a PC with EnerVista PQM Setup or third party software. Distorted peaks or notches from SCR switching provide clues for taking corrective action.
