overview

• vlf, dc and sheath fault testing in one device
• portable thanks to two-part construction
• high test capacitance
• integrated discharge system
• reporting

the portable, high-performance and energy-efficient vlf test systems are used for testing cables with 0.1 hz cosine-rectangular voltage according to iec/ieee/cenelec standards. in accordance with guidelines, the dielectric strength of cables and joints must be checked after installation or repair.

the vlf test systems from sebakmt have high test-capacities and are still compact, because of the patented voltage wave-shape and the power-recycling during polarity reversal. aside from cable and sheath testing, the test systems can also be used for the precise pinpointing of sheath faults (in combination with a step-voltage probe).

in total three portable systems are available, each with different voltage levels (28, 40 and 60 kvrms):

• vlf cr-28 up to cable series 15 kv
• vlf cr-40 up to cable series 23 kv
• vlf cr-60 up to cable series 35 kv
