High voltage cable metal sheath is usually cross-bonded in the cable cross connection box in order to reduce the metal sheath voltage. Because of the complexity of the cable laying environment, cross connection box will appear damp, water, external damage or other situations, leading high voltage cable metal sheath cross fail in link box, buried the hidden trouble to the safe operation of the whole system.

SSET has developed a contactless voltage transducer which applied to measure the cable voltage. It can be easily fixed on the installed cable without disconnecting the equipment cable.Therefore, non-contact voltage transducer is more convenient and safer than the traditional current transducer.
