Megger VLF CR-40 Portable VLF Test System

Megger VLF CR-40

The Megger VLF CR-40 Portable VLF Test System is a versatile and powerful tool designed specifically for testing the insulation of medium-voltage cables and other electrical apparatus. This system is particularly well-suited for utilities, industrial plants, and service companies that require reliable testing methods to ensure the safety and longevity of their electrical infrastructure. Below is a detailed overview of the key features and benefits of the Megger VLF CR-40.

Using a 0.1 Hz cosine-rectangular voltage, weak points in the cable can be safely broken down during testing. The effectiveness of the VLF method with this voltage waveform has been validated through numerous scientific studies and practical field applications. Since the patent was granted in 1987, over 2,500 systems have been sold globally. This reliable voltage waveform is recommended by the CENELEC HD 620 and HD 621 harmonization documents, as well as the IEC 60502-2 and IEEE 400.2 standards.
