The Megger DET4TCR2 is a versatile four-terminal ground resistance tester with clamps, designed for electrical professionals who demand precision and reliability. It evaluates the safety and integrity of electrical systems by measuring earth ground resistance, soil resistivity, and ground voltage. With True RMS technology, it delivers accurate readings even in the presence of harmonics and noise, making it ideal for industrial environments.
Key Features & Highlights
- Multiple Testing Methods: Supports 2-, 3-, or 4-pole ground resistance testing, plus ART (Attached Rod Technique) and clamp-on (stakeless) tests for flexible field use.
- True RMS Measurement: Ensures accurate current and voltage measurements in noisy environments.
- Wide Measurement Range: Ground resistance from 0.01 Ω to 20 kΩ, ground noise from 1 V to 100 V, and ground current from 1 mA to 20 A.
- Selectable Test Voltage: Easily switch between 25 V or 50 V to comply with local testing standards.
- Rugged and Portable: IP54-rated enclosure for outdoor operation, with a bright backlit display for dark locations.
- User-Friendly Design: Rotary range selector and one-touch test button allow operation with gloved hands.
Applications
The Megger DET4TCR2 is essential for utility, industrial, and commercial electricians, as well as maintenance professionals. It is used for verifying grounding systems in substations, transmission towers, and industrial plants, and for soil resistivity testing in new installations. Its ART capability allows testing without disconnecting the utility connection, saving time and improving safety.
