MEGGER VLF Sine Wave 34 kV CABLE TESTER

The MEGGER VLF Sine Wave 34 kV Cable Tester stands out in the industry as a compact, robust, and portable Very Low Frequency (VLF) sine wave test system specifically designed for medium voltage cables. Engineered for ease of transport and rapid setup, this tester is the perfect solution for routine cable testing tasks, proving essential for maintenance and testing professionals.

This system is versatile, supporting not only 0.1 Hz sine wave voltage tests but also rectangular or DC voltage tests, thereby meeting the highest standards for test voltage quality and stability. Such capabilities make it a highly reliable tool for comprehensive cable testing regimes, ensuring that all testing is conducted thoroughly and efficiently.

A critical feature of the MEGGER VLF Sine Wave 34 kV is its integrated breakdown detection. This function automatically shuts down the test voltage in the event of an excessive charge current. This safety feature is crucial as it helps to prevent extensive damage to the cable under test, thereby protecting the investment in the cable infrastructure while ensuring the safety of the operating personnel.

Additionally, the VLF Sine Wave 34 kV is not only limited to cable testing but is also adept at sheath testing and, when used with the optional step voltage probe ESG NT, can effectively pinpoint sheath faults. This makes it an invaluable tool in diagnosing and resolving cable sheath issues, which are critical for the integrity and longevity of cable networks.

The flexibility of the MEGGER VLF Sine Wave 34 kV extends further as it can serve as a voltage source for additional diagnostic procedures such as tan delta measurements and partial discharge tests when attached to the optional diagnostic modules. This ability to expand its functionality makes the VLF Sine Wave 34 kV a universal testing and diagnostic system, adaptable to a wide range of testing scenarios and needs.
