Description
Key Features:
- Large Caliber Clamp: The ETCR7300 Large Caliber Three-Phase Clamp Power Meter is equipped with a clamp size of 80mm x 80mm, allowing it to easily clamp cables up to φ80mm in diameter or 96mm x 4mm flat steel grounding leads, making it ideal for diverse field applications.
- Comprehensive Measurement Functions: This multi-functional power meter is capable of measuring three-phase AC voltage, current, frequency, power factor, and more, making it suitable for comprehensive electrical system analysis and diagnostics.
Versatile Applications:
- Transformer Diagnostics: The ETCR7300 series is designed for tasks such as distinguishing transformer wiring groups, identifying inductive and capacitive circuits, and checking the phase relationships between differential protection CT groups. It can also verify correct wiring of electric meters and assist in equipment maintenance.
- Data Storage & Upload: The meter comes with data storage capabilities that can store up to 200 sets of measurement data. Through the RS232 interface, users can upload stored data to a computer for real-time monitoring, historical data queries, and report generation, streamlining data management.
Durable & Reliable:
- Anti-Interference Technology: The ETCR7300 power meter is built with a special alloy iron core and features advanced magnetic shielding technology. This ensures minimal interference from external magnetic fields, guaranteeing long-term stability and high measurement accuracy, even in complex electrical environments.
- Backlight & Data Hold: With backlight functionality and data retention, this power meter is designed for ease of use in both bright and dim environments, making it an indispensable tool for electrical safety testing and field inspections.
