VLF Sine Wave 62 kV
Test and diagnostic system for the testing and condition analysis of medium voltage cables
- Performs cable withstand testing, cable diagnosis and sheath fault pinpointing
- Smallest and lightest unit on the market in its class
- Automatic result interpretation as per latest IEEE 400.2 standard
- Easy field operation with no need for external computer
The VLF Sine 62 kV, with integrated tan delta, is a compact, robust, and portable high-performance test and diagnostic system for medium voltage cables.
The VLF Sine 62 kV tester is a multifunctional tool. Not only can it perform VLF and DC testing, but it can also perform sheath testing and sheath fault pinpointing. Moreover, 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.
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
The VLF sine wave 34 kV is a compact, robust and portable VLF sine wave test system for medium voltage cables.
The design, optimized for rapid transportation and quick setup, and the continuous duty cycle are two attributes that qualify the system
as 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.
Consistent single-button operation combined with a sophisticated operating concept allows a fast and targeted use of the system.
