特性

• Electric motors and inverter drive systems – Through detailed spectrum analysis and dynamic torque calculation capabilities, switching losses caused by the inverter are accurately measured, and a thorough evaluation is made of torque transients and harmonics at higher frequencies.
• Inverter drive system – Simultaneous measurement of all electrical and mechanical power parameters in the same time window enables users to observe the influence one component has on another, or on the whole system.
• Lighting systems – A wide bandwidth of up to 10 MHz and a high sampling rate up to 1 MHz provide detailed signal analysis at ballast outputs. A unique shunt technique enables power measurements at very high frequencies. Simultaneous measurement of input and output power provides instant calculation of ballast losses.
• Transformers – Synchronous six-phase power measurements enable highly accurate efficiency and loss calculations of large power transformers even at very low power factors. Synchronous multiphase resistance measurements of transformer coils are also possible.
• 汽车-同步电气输入和机械输出测量提供了有关单个部件以及整个驱动系统的效率和损耗的完整数据。
• 变压器-同步六相功率测量使大型电力变压器即使在非常低的功率因数下也能进行高精度的效率和损耗计算。同步测量变压器线圈的多相电阻也是可能的。
• Automotive – Synchronous electrical input and mechanical output measurements provide complete data on the efficiency and losses of individual components as well as the whole drive system.
