Megger now offers two earth/ground digital clamp-on resistance testers that are easy to use, versatile and safe. Testing with the DET14C and DET24C can help prevent a rise in voltage caused by fault current, surges and lightning strikes in earth/ ground systems.
The new testers offer improved reliability over other testers with interlocking teeth. Designed with flat core ends that help prevent dirt build up and ensure measurement integrity, these new elliptical shaped clamp testers are ideal for a variety of applications. Uses include pole grounds, service entrance/meter electrodes, service panels, pad mount transformer earth, transmission towers, telephone pedestals, telephone cabinets and lightning protection electrodes.
The slim profile and clamp design of the two units allow for easier access and testing of round conductors. The DET14C and DET24C can clamp round cables up to 37 mm in diameter and earth tapes/straps up to 50 mm wide. These testers can measure ground resistance from 0.05 ohm to 1,500 ohm and true RMS ground leakage current up to 35 A.
The units feature a large backlit digital display for low light conditions, a noise filter function that alerts the user to the presence of noise during testing as well as an alarm limit function that can be set for resistance and current limits. Both the DET14C and DET24C offer advanced test result management that includes time and date stamp stored results that can be reviewed on screen.
The DET24C offers additional features including an IrDA USB interface to a PC, advanced memory functionality that can transfer data to a PC or a laptop, as well as compatibility with Megger’s PowerDB/PowerDB Lite acceptance and maintenance test data management software.
Both the DET14C and DET24C are safety rated to CAT IV 600 V, the highest level of safety available. These dependable units feature ultra-long battery life.
