Delivering up to 30 kV damped alternating current (DAC) output, the Megger MV DAC-30 is engineered for comprehensive testing of medium voltage cables. Its advanced diagnostic software and integrated partial discharge measurement enable users to identify cable faults and assess cable insulation conditions swiftly and accurately, reducing outage risks and maintenance costs.

Designed for Versatile Environments

With IP54 protection, robust powder-coated steel housing, and operation in temperatures from -20C to +55C, the MV DAC-30 is built for durability. Its four heavy-duty locking wheels and portable design allow for easy movement across substations, industrial sites, or field environments, while the user-centric touchscreen and remote operation support facilitate convenient, on-the-spot or remote diagnostics.

FAQ's of Megger MV DAC-30 Damped AC Cable Test and Diagnostic System:

Q: How does the Megger MV DAC-30 improve cable diagnostics compared to conventional methods?

A: The MV DAC-30 uses a 30 kV DAC waveform combined with advanced diagnostic software, enabling precise partial discharge measurement and localization. This capability allows users to detect insulation degradation and pinpoint defects in medium voltage cables more accurately than traditional VLF or DC testing methods.

Q: What types of cables and applications is the MV DAC-30 best suited for?

A: This system is specifically designed for medium voltage power cables in utilities, industrial plants, and infrastructure projects. Its high current and broad capacitance range make it ideal for commissioning, maintenance, and fault location tasks on modern cable installations.

Q: When should I use the partial discharge measurement function during testing?

A: Partial discharge (PD) measurement should be performed during all routine or diagnostic tests, as it helps assess cable insulation integrity and identify incipient faults before they develop into critical failures. The MV DAC-30's integrated PD function provides real-time analysis during each test cycle.

Q: Where can test results from the MV DAC-30 be accessed and how are they stored?

A: Test results are saved directly to the system's integrated memory and can be exported via USB or Ethernet ports. Additionally, results are accessible on the 7-inch touchscreen or remotely through network connectivity, streamlining data management and reporting.

Q: What is the process for operating the MV DAC-30 on site?

A: To operate, connect the system to mains power, ensure safety interlocks and earthing checks are in place, select the desired test cycle via the touchscreen, and follow on-screen prompts. The system automatically carries out measurements including PD, capacitance, and insulation assessment, generating a comprehensive report at the end.

Q: What are the main benefits of using the MV DAC-30 in the field?

A: Benefits include high diagnostic accuracy, automated reporting, robust environmental protection (IP54), corrosion-resistant build, and simple transportation. The combination of onboard data storage, remote operation, and integrated safety features ensures efficient and safe cable assessment in diverse field conditions.
