MEGGER HV DAC series Test And Diagnostic System For Hv Cables

The MEGGER HV DAC series represents a cutting-edge test and diagnostic system specifically engineered for high-voltage (HV) cables. This series is adept at conducting after-laying testing on newly installed HV cables, which forms a crucial part of quality control. Additionally, it’s invaluable for condition assessments on repaired or service-aged HV cables, ensuring that they continue to meet safety and performance standards.

One of the standout features of the HV DAC series is its remarkable compactness relative to its testing capacity. This transportable unit can effectively test cables up to 32 kilometers in length, demonstrating significant technical prowess without the bulk typically associated with such capabilities. The compact nature of the device not only facilitates easy transportation but also simplifies setup within substations. Unlike resonance test sets that often require large trucks and roadblocks during setup, the HV DAC series eliminates these logistical challenges, offering a more streamlined and less intrusive testing process.

The portability of the HV DAC series also brings a high degree of operational flexibility. With its quick setup time, the system allows technicians to efficiently adapt to changing weather conditions—a critical advantage when working in outdoor environments. The system’s low weight further underscores its portability, eliminating the need for special road accommodations and making it suitable for air transport. This capability significantly reduces transport times, enhances the system’s overall efficiency, and ensures that testing and diagnostics can be carried out promptly and effectively, no matter the location.
