Today power inverters are being broadly applied as the energy-saving performance of electrical devices continues to improve and solar power systems become increasingly popular. Yet while inverters are contributing to both of these trends, they also emit harmonics that can interfere with the proper operation of electrical devices and the electronic components they use. Demand for harmonic analysis capability is growing due to the need to limit its adverse impacts.

Key Features:

Analyze harmonics up to the 40th order

The PW3360-21’s harmonic analysis function can analyze harmonics of up to 40 times the fundamental wave, or the 40th order. The power logger can display a variety of measurement parameters, including harmonic RMS values, content percentages, and phase angles, in both list and graph form. The logger can also save measured values on an SD memory card at a user-specified interval. Moreover, the optional Power Logger Viewer SF1001 PC application can be used to display time-series graphs of harmonic data on a computer, further aiding in harmonic analysis.

Features Shared with the Clamp On Power Logger PW3360-20:

• Extensive measurement capabilities in a compact package
• Graph display that provides an instant understanding of power utilization (new feature)
• Quick Set navigation helps prevent measurement mistakes
• Leak current measurement and pulse input for expanded capabilities
• Continuous operation, even in locations where AC power is unavailable
