Fluke 1621 Earth Ground Tester
Fluke 1621 Earth Ground Tester
Product Description :
- It is a specialized instrument used to measure the effectiveness of an electrical grounding system (also called an “earth” system). It is crucial for ensuring the safety of electrical installations by verifying that the ground system provides a low-resistance path for fault currents to flow into the earth, reducing the risk of electrical shock, fire, or damage to electrical equipment.
- The unit features basic ground testing methods including 3-pole Fall-of-Potential as well as 2-pole ground resistance tests. Its convenient size, rugged holster, and large, clear LCD display make it an ideal field earth ground tester, for most electrical grounding work environments. With a simple user interface and intuitive functionality, it is a handy grounding tool for electrical contractors, utility test engineers, and earth ground specialists.
-
An Earth Ground Tester is a precision instrument designed to measure the resistance of grounding systems, ensuring electrical installations are safe, efficient, and compliant with standards. It evaluates the effectiveness of earthing by detecting faults, loose connections, or high-resistance paths that can compromise safety.
-
Equipped with advanced measurement technology, earth ground testers can perform three-point, fall-of-potential, or clamp-on testing methods, depending on the application. They feature digital displays, robust housing, and user-friendly controls for accurate and quick field measurements, even in challenging environments.
-
Commonly used by electricians, maintenance teams, and safety inspectors, this device is essential for verifying that grounding systems protect people, equipment, and infrastructure from electrical faults and lightning strikes.
