Dranetz 658 Power Quality Analyzer

The Dranetz 658 offers a comprehensive suite of features for power quality analysis:

• True RMS Voltage and Current Measurement: Accurately measures voltage and current in both AC and DC systems.

• Scope and Meter Modes: Provides real-time waveform displays and detailed metering capabilities.

• Event Monitoring: Utilizes a report-by-exception approach to identify and log power quality events.

• Harmonics Analysis: Analyzes harmonic content to assess power system quality.

• High-Speed Sampling: Offers cycle-by-cycle disturbance capture with a sampling rate of 7.2 kHz per channel for RMS measurements and 1.85 MHz per channel for impulse measurements.

• Multiple Transient Capture: Simultaneously captures multiple transients and complex waveforms.

• Auto-Ranging: Automatically adjusts measurement ranges for optimal accuracy.

• Simultaneous Channel Capture: Allows for concurrent monitoring of multiple channels.

• Graphic Summaries and Zoom Functionality: Provides visual summaries with the ability to zoom in on specific events for detailed analysis.

• Transducer Inputs: Supports additional measurements through external transducers.

• Built-in Floppy Drive: Facilitates data storage and transfer via a 3.5-inch floppy disk drive.

• DRAN-VIEW PC Analysis and Report Writer Software: Enables comprehensive data analysis and reporting on a personal computer.
