Accurately Pinpoint Power Problems with the 400 Series Fluke Power Quality Analyzers

  • Uncategorized

An electrical system should have a clean sinusoidal waveform to ensure maximum power transfer to the connected loads. When the power quality is poor, the distortion causes electrical losses and affects the operating life of the loads connected to the electrical facility. Harmonics, voltage spikes, sags and swells are some of the common causes of power quality deterioration. These are often generated by the equipment connected to the electrical line. In order to assess power quality, analysis instruments are used. These devices isolate and measure each type of distortion present to help the engineer in properly suppressing the waveform distortion and interference.

Fluke Power Quality Analyzers are the ideal instruments for power quality measurement and trends analysis. The Fluke 430 Series of Analyzers is one of their popular product lines for pinpointing power problems. They feature an on-screen display for trends and power events and continuous to record parameters in the background. This makes troubleshooting faster and easier. Read on for a comparison of features of each tester.

Fluke 434 Analyzer

This analyzer offers single and multiphase power quality analysis with an automatic transient mode that captures 200 KHz waveform information on all phases. It is fully compliant to the new IEC standards for measuring harmonics, flicker and other power quality parameters to reduce the guess work in diagnostics.
