High frequency current on-line monitoring system
SML1000 intelligent detection ecological series products
Intelligent detection is a major issue for the planning and construction of the ubiquitous electric power Internet of Things system by the State Grid Corporation of China. It is also a key application for solving the problem of interconnection and data sharing of the operation inspection system. It is also an important basis for the practical application of big data analysis for equipment inspection.
ZY-PDM1000U online monitoring system
A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It is a key device in the power system. Generally, transformers rarely fail. Once a certain defect occurs inside the transformer equipment, equipment failure is extremely easy to occur. Therefore, strengthening and improving the operation monitoring of transformer equipment is of great significance for ensuring the safe operation of transformers.
DXK-ZY high voltage live display
