Metrel MI 3290 GF Earth Analyser

Description

The Metrel MI 3290 GF Earth Analyser is a high-performance, portable instrument specifically designed for comprehensive earth ground testing in challenging environments. It builds upon the capabilities of the standard MI 3290 model by incorporating features optimized for grounding systems with high ground resistances.

Key Features and Capabilities:

• Possibility of performing different types of earth measurements with a single instrument.
• Analysis of earth impedance as a function of the frequency due to a wide measurement frequency band (55 Hz … 15 kHz).
• Earth measurements on pylons with protective earth cable connected.
• Sweep mode Z(f) on screen.
• High resolution colour touch screen, 4.3” TFT.
• Floating Mains (universal 90 … 260 V AC) or battery powered (built in fast charger).
• High degree of protection: IP 65 case closed, IP 54 case open.
• Checkbox – different self-check methods.
• DC resistance measurements.
• Support for single or automated measurements.
• PC SW for measurement pre and post processing: preparation of the test structure, result download, tree-view, table view and graphical view, storing and printing.

Applications:

• Testing High Resistance Grounding Systems: Ideal for testing grounding systems in applications such as substations, pipelines, and remote locations where ground resistances are typically high.
• Troubleshooting Grounding Problems: Identifying and diagnosing problems with earth grounding systems, including high resistance, poor grounding connections, and stray currents.
• Ensuring Safety: Ensuring compliance with safety standards and regulations related to earth grounding.
• Investigating Grounding-Related Incidents: Analyzing grounding-related incidents to determine the root causes and prevent future occurrences.

Overall, the Metrel MI 3290 GF Earth Analyser is a specialized tool for professionals who require accurate and reliable earth ground measurements in challenging environments with high ground resistances. Its advanced features, combined with its rugged design and user-friendly interface, make it a valuable asset for ensuring electrical safety and system integrity.
