Allows testing of round cables/rods up to 37 mm dia and ground tapes/straps up to 50 mm width
- Smooth mating surfaces on the clamp head is easy to clean with no interlocking teeth to damage
- CATIV 600 V rated offering highest level of user safety allowing you to use units safely before the distribution board
- Noise filter function selection increases noise immunity allowing the units to be used in higher electrical noise environments
- Resistance and current limit alarm functions (visual and audible) to set min/max limits reducing test time and improving accuracy
- Intelligent data hold function increases instrument ease of use in difficult testing locations
- Data storage (both models)/results downloading (DET24C) reduces potential for error in recording results
- Time and date stamped results provides improved data/results management and accuracy of result reporting
- New ergonomic trigger design is easier and more comfortable to operate with less chance of slippage causing the head to snap shut
Feature details of the DET14C and DET24C testersThe DET14C and DET24C are advanced clamp-on ground resistance testers that set new standards in terms of access, performance, features, simplicity of operation and safety. The DET14C and 24C are used to measure earth/ground resistance in multiple loop installations without disconnecting the ground.
Designed with flat core ends, these units prevent dirt build-up, ensuring measurement integrity and improved reliability over products with interlocking teeth. Other enhancements include safety to CATIV 600V, a built-in filter function for electrically noisy environments, time and date stamped stored test results and ultra long battery life. Megger has taken what is now a standard test method and significantly improved its field applicability.
The DET14C and DET24C are designed to quickly measure ground electrode resistance in applications where this type of test method can be used and/or verify the integrity of ground connections. The goal of ground resistance testing is to ensure that the resistance ground electrode system is low enough to prevent or limit voltage rises caused by fault current, electrical surges, lightning strikes, etc.
Clamp-on ground testers work in applications where there is a loop resistance to measure with ground paths in the system (the more ground paths, the closer to the actual resistance). A utility pole ground system is a classic example of this type of application.
