Megger EZ-THUMP 3 kV and EZ-THUMP

The Megger EZ-Thump series, encompassing the EZ-Thump 3 kV and EZ-Thump 4 kV models, represents a significant advancement in portable fault location technology for low voltage power cables, both shielded and unshielded. These systems are designed to offer utility and industrial professionals a highly portable, efficient, and intuitive solution for rapid fault detection and resolution in electrical cable networks.

Key Features of the EZ-Thump Series:

• Surge Energy: The EZ-Thump 3 kV delivers dual-stage 500 J surge energy at 1.5 kV and 3.0 kV, optimizing it for various fault conditions, while the EZ-Thump 4 kV provides a single-stage 500 J surge energy at 4.0 kV, making it ideal for more demanding applications.
• Safety Features: Both models feature the F-OHM HV interlock, ensuring safe earthing and operation, which is critical in preventing accidents during high-voltage testing.
• Flexible Operation: These units can be operated using either AC power or their internal batteries, enhancing their versatility in field applications where power sources may not be readily available.
• Advanced Fault Locating: Automatic end-of-cable and fault location combined with ARM pre-location and fault pinpointing (thumping) make the EZ-Thump series exceptionally effective at not only detecting but also precisely locating faults.
• User Interface: A transflective color display ensures clear visibility under various lighting conditions, and the “Easy Go” test system simplifies the operation, making it accessible even for technicians with minimal training.
• Portable Design: Weighing as little as 32 kg and compact enough to fit in the trunk of a car, these units are designed for mobility, providing a quick response capability that is essential for minimizing downtime in power distribution networks.
• Comprehensive Testing Capabilities: The built-in Time Domain Reflectometer (TDR) with a range of up to 7.6 km and arc reflection methods at respective voltage levels provide reliable pre-location of faults. The systems also support DC testing for breakdown detection and measure insulation resistance, enhancing their diagnostic capabilities.
• Additional Functionalities: Both models can perform sheath fault testing and location, adding another layer of diagnostic utility and making them indispensable tools for comprehensive cable maintenance.
• Optional Features: The EZ-Thump series can be equipped with optional sectionalizing software, which further enhances its fault analysis capabilities, allowing for more detailed and segmented analysis of cable networks.

The Megger EZ-Thump 3 kV and EZ-Thump 4 kV are not just tools but solutions tailored to meet the demands of modern cable fault location tasks. They combine portability with powerful diagnostic features, making them ideal for a variety of environments, from urban utility applications to industrial settings where rapid fault resolution is critical. Their ease of use, combined with advanced technology, ensures that both routine checks and emergency fault location can be conducted quickly, safely, and effectively.
