VLF Sine Wave 62 kV

VLF sine wave test system for medium voltage cables

  • Performs cable withstand testing, cable diagnosis, and sheath fault pinpointing
  • Smallest and lightest unit on the market in its class
  • Unique user-experience, thanks to a large, colour touch screen
  • Automatic result interpretation as per latest IEEE 400.2 standard
  • High safety, thanks to its analogue residual voltage indicator

The VLF Sine 62 kV, with integrated tan delta, is a compact, robust, and portable high-performance VLF sine wave test system for medium voltage cables.

The 62 kV tester is a multifunctional tool. In addition to VLF and DC testing, it can also perform sheath testing and sheath fault pinpointing when used in combination with the step voltage probe ESG NT/ NT2. Furthermore, the optional internal tan delta expands the system to assess both cable integrity and condition. The smart VLF system automatically adjusts the test frequency to the cable length, making even tests on 35 kV rated cables (up to 25 km) easy and reliable.

Field operations require no external computer. Equipped with intuitive operating software and a large internal memory, the VLF sine wave 62 kV evaluates and stores all data automatically. 

Using either a USB port or wireless connection to mobile end-device (coming soon), datasets can be easily exported and processed for report generation via the PC software MeggerBook Lite (included in delivery). What's more, you can review all performed measurements either immediately or at a later point in time on the unit itself.

VLF Sine Wave 62 kV Datasheet

VLF CR-60HP and VLF CR-80

Cosine Rectangular Cable Testing

 
  • Very high test power without frequency reduction
  •  Covers cables up to 20 km at maximum voltage
  •  No polarisation effects as with DC
  •  Protocoling
  •  Breakdown detection
  •  Leakage current measurement

Powerful 0.1 Hz VLF test system with energy recovery for testing of cables with Cosine Rectangular Wave voltage according to VDE, IEC and IEEE.

In accordance with most regulations, cables and joints must be tested after installation or repair. The Seba KMT VLF Test System CR 60 kV can be used to test cables with operating voltage levels up to 36 kV. The system consists of a control unit and a HV unit. The high test capacity of 6.5 μF permits the simultaneous testing of all three phases. Positive and negative DC testing of cables and connected switchgear can be carried by DC Mode.

This VLF Test System CR 60 kV can be used both as a stand alone system and as integrated part of a test van system.

VLF Sine Wave 34 kV

Sine Wave VLF System

  • High test capacity of 5 µF
  • Suitable for outdoor use (IP 54)
  • Single-button operation
  • Integrated safety system
  • Reporting
  • Continuous duty cycle

The VLF sine wave 34 kV is a compact, robust and portable VLF sine wave test system for medium voltage cables. It's optimised for rapid transportation and quick setup, and is an ideal tool for routine cable testing. For both 0.1 Hz sine wave voltage tests and rectangular or DC voltage tests, the VLF sine wave 34 kV fills the highest demands on the test voltage quality and stability. Moreover, the integrated breakdown detection shuts down the test voltage in the event of an excessive charge current and guarantees limited damage to the cable.

The VLF Sine Wave 34 kV can be used for cable testing, sheath testing and, in combination with the optional step voltage probe ESG NT, sheath fault pinpointing. The system can also be used as a voltage source for the optional tan delta measurement and partial discharge attachments, and can be easily expanded to a universal testing and diagnostic system.
