Professional manufacture overhead line short circuit and ground and earth fault indicator locator for power distribution network
The fault indicator is used in overhead lines of a network. Its function is to survey the net continuously for permanent faults and temporary faults. The indicator can be mounted under live conditions with the help of an adapter and a hot stick. It is completely self-sustained by the monitored network from a current flow of 30A upwards. The indication is done by six ultra-bright flashing LEDs for a clear nighttime and three red display areas for a clear daytime visibility.

Self-sustain |
Indication |
|
The indicator is made with new material and special circuit designed. When the wire’s load current is greater than 3A, it begins to get the power from the wire. When the wire load current is greater than 15A, it can work normally without the lithium battery totally. |
The indication is done by three flashing LEDs for a clear visibility and three red display areas work by motor for a clear daytime visibility. Single-flashing means ground fault indication; double-flashing means short-circuit fault indication. |

Ground fault detection |
Short-circuit fault detection |
|
It can monitor the mutational increment of the grounding current (the parameters can be set on-line so that the detection can be more sensitive and reliable). |
1. Quick break and over-current criterion. It can be set online or by PDA. It can suppress inrush current and feedback power supply, so that it can ensure the consistency of the operation with the substation outlet. 2. Adaptive load current criterion. |

Live mounted and removal |
Current and voltage measurement |
|
The indicator can be mounted under live conditions with the help of an adapter and a hot stick. |
Real-time monitoring of line load current, wire-to-ground voltage induction, instead of using current transformers and live displays. |
|
Reset mode |
Anti-rust design |
|
The tension discs are made of high-quality nylon material. The groove springs are made of stainless steel so that they won’t melt with the wire. The thread jamming structure parts are made of stainless steel and with antirust design. |
|
Anti-refuse operation design |
Anti-misoperation design |
|
We adopt large cross-section design of magnetic circuit, it has good permeability performance, accuracy measurement and high sensitivity. They can be very sensitive no matter in the rural power line small load current or small mutations conditions or in the city network line two phase short circuit or slow flow conditions. |
It has anti misoperation design, when the inrush current occurs after the non-loading line is switched on and anti misoperation of non fault branch when it’s on. |

Communication mode |
Auto-upgrade |

Embedded short-range two-way wireless communication frequency RF modules, the GPRS data can communicate via data collection terminal or wireless repeater. |
Parameters can be dynamically modified and automatically upgraded online at any time to achieve better and more economical services. |

Founded in 2005, Zhuhai Gene Cosmos Electric Technology Co., LTD. is located in Zhuhai, a beautiful coastal city in China, which is a Chines-foreign joint venture. Since its establishment, the company developed rapidly. She has been awarded as “Guangdong Province Observe contracts and keep promises enterprise”, “The best private technology enterprise in Zhuhai”, “Guangdong high-tech enterprise”. With its own intellectual property, she has acquired more than 20 product patents successively.
Our company has been committed to the technology development and application of distribution line real-time monitoring. Cooperating with Genetic Technology(U.K.)Ltd., an English company, brought in Smart Line, its latest technology used in distribution line monitoring system. Through this system, we can monitor the parameters of cables and other electrical equipments real-timely as its advanced technology. At the same time, we improved this system according to Chinese market. We brought out a series of products which are matching the leading of distribution network automation like fault indicators, cable temperature accurately measuring solution, high voltage live display& locking device, high accuracy multifunction power meter, integrated microcomputer relay protection device, integrated environment monitoring system, electricity information collection terminal.
Nowadays, our company hasn’t slowed down the pace of progress, instead, we keep on developing the latest fault wave recorded products and integrated solution of on-line analysis for distribution network. We improve the precision of fault detection through high-speed recording technology and rapid analysis system. In this way, we can solve the difficult complex problems.
