We are offering arc suppression coil neutral earthing. 1、company information we are a leading manufacturer of the neutral grounding electric equipments in china and we have many years experience in this line of business. Our products are also exported to asia, africa, russia, the united states, and the middle east. We have cooperation relationship with abb, siemens, teba, hyosung, alston and so on, we want to build a long time cooperation relationship with your company. 2、system description tht-pxhk(c) system is mainly used for 6kv-66kv neutral ungrounded power grid and also widely applies to high voltage distribution networks in mining , coal , chemical industry and larger cities . With normal grid operation, the system provides real-time monitoring of network capacitive current. When occurs single-phase grounding, it will automatically enter compensation state and implement optimal compensation for the grid capacitive current. The fault residual current will be less than 5a, which can effectively suppress the arc over-voltage, thus prevent failures arising like phases short circuit etc. The system can be customized to set for ideal state as per user requirements. 3、system composition tht-pxhk system consists of three units: microcomputer control cabinet, biasing magnetic arc-suppression coil body, grounding transformer (optional to users). The grounding transformer and arc suppression coil can either dry or oil immersed. The microcomputer control cabinet is with standard screen, which includes automatic tracking compensation controller, dashboard and rectifier etc.

We are offering neutral grounding resistor cabinet for generator. 1 purpose the tht-fzg generator neutral grounding resistor cabinet can protect generator stator by high-resistance grounding.mainly grade for the generator voltage is from 6 kv to 20 kv. When the stator one-point earthing occurs, it can limit the grounding current in a small value and effectively suppress arc grounding transient overvoltage 2、product feature 1）cabinet material : stainless steel plates or hot dip al-zn coating steel or cold-rolled steel plates or galvanized plate. 2）installation ：general indoor. 3）generator neutral grounding resistor ark also equip single-phase disconnector so that it can isolate power supply during the test and repairs. 4）our company has researched intelligent control unit which can monitor more data than counter and transfer the data to the mainly control room. 5) the neutral and phase side cubicles or terminal box shall be of the metal enclosed, dust, insect and splash-proof type and ip00- ip55 protection degree.
