Megger HV DAC-300 – Test and Diagnostic System

• DAC voltage up to 300 kV peak for cables rated to 230 kV
• Integrated withstand testing and partial discharge diagnostics
• Compliant with IEC 62067 and IEEE 400.4 commissioning standards
• Automatic calibration with live PD mapping and localisation
• Modular portable design with notebook control and flight cases

The Megger HV DAC-300 combines damped AC testing and partial discharge diagnostics in one transportable system. It generates realistic voltages close to power frequency, enabling accurate PD evaluation and precise fault location. The software guides users through the entire process with automatic calibration and live mapping, producing clear results and reports at the click of a mouse.

Packaged in rugged flight cases for rapid air transport, the system fits easily into substations and requires minimal power. An optional support capacitor extends its use to shorter cable lengths. Whether commissioning new circuits or assessing aged ones, the HV DAC-300 delivers reliable data for timely maintenance decisions.
