As people's emphasis on environmental protection, the environmental testing and control domain are also in rapid development. The environmental detection objects can be roughly divided into water quality inspection, air monitor , soil detection, solid waste test, , biological detection, noise and vibration detection, electromagnetic radiation detection, ionizing radiation test, thermal test, optical testing, health (pathogens, viruses, parasites), etc. Through the use of the instrument to detect the content of various substances and emissions. Thus it will be good to track the change of environmental quality, determine the environmental quality level. Thereby it will lay the foundation and guarantee the environment management and pollution control. It is the premise of all environmental work.
It results critical to know the network topology data in order to maintain a correct management of electrical distribution networks. Therefore, it´s essential to know HOW and WHERE each of the LV assets/consumers are connected, to which transformer-feeder-phase.
