| Our complete device of arc & harmonic control and voltage protection is based on innovative theory, with full function and high automation. It could quickly eliminates electric arc, arc flash transient overvoltage, ferromagnetic resonace associated with ground fault by increasing current instantly to locat the ground line accurately, widely used in 3-35kv power grid in eletricity, metallurgy, chemical enterprises, coal mining, petroleum and industries like such. Main Functions 1.To replace PT cabinet and supply testing signal of voltage 2.With function of voltage protection, the device could limit atmosphere overvoltage and operating overvoltage at a lower level, so as to ensure insulation safty of power grid and electric equipment and reduce accidents casued by overvoltage a lot. 3. To replace arc-suppression coil, eliminate intermittent arc-grounding fault quickly, suppress intermittent arc-grounding overvoltage, prevent accidents from deteriorating and reduce accidental trip probability of wire. 4. To limit and eliminate various resonant overvoltage quickly and effectively, prevent aging-acceleration of system insulation structure caused by long time resonant overvoltage, avoid resonant overvoltage effection to power grid setting like arrester as well as small inductive load, increase safty & stability of system operation, and lengthen lifetime of system equipment. 5. To look up single-phase faulty wire accurately and quickly, prevent accident from deteriorating, reduce workload of operation and maintainance people. 6. The device possesses the function of switching TV. |
- Q:Rivers and lakes emergency, there is a 110kV and 10kV power supply line works, I would like to ask this kind of power project warranty items, scope, life and other detailed provisions where can be found? Are there relevant regulations?
