Cable surge voltage limiters box
10kV and above three-core cable is due to pass three core current can be seen on cable protective layer current is zero, and the single-core cable wire and metal sheathing, can be seen as a transformer primary and secondary groups around the group around, when the current through the cable wire, around the magnetic part Line will pay Metal Jacket chain, sheathing have induced voltage, the voltage sensor size and the length of cables and wires flowing directly proportional to the current. If the cable at both ends of metal sheathing while grounding, the metal sheathing will be formed on the current, conductor and metal sheathing fever also makes cable insulation aging, while lowering levels of insulation, causing the cable to reduce life expectancy. To this end should be adopted grounding, end-use security protection (box) ground in the form of operations, such as security guards-voltage reaches a certain value, retaining layer protection (MTL), instant action, the release of current, safe operation requirements.
As the currents run through the three cores simultaneously in the 10 kV and the higher voltage three-core cable ,we deem that the magnitude of the current in cable finish is zero .However ,as for the single-core cable ,the
