Research of Portable Insulation Detecting Device which Based on for Electric Equipment

The insulating state detection of capacitive equipment has been a long time, but the actual effect is not satisfactory. It mainly because low-precision measurement and cannot overcome the location interference which can cause mutation of measured data. The reliability of the device is low. This has seriously affected the popularization and application of the state detection technology. According to current situation of capacitive equipment insulation monitoring, a kind of portable distributed charged detection device prototype of capacitive equipment dielectric loss and capacitance detection is developed, which based on high precision GPS synchronous sampling technology and the Internet of wireless sensor network technology. And it uses the relative comparison method of dielectric loss analysis algorithm to overcome data fluctuation caused by factors such as the current leakage along the surface. Experiments show that the devices realize high precise collection of the state data. It has widely application prospect.
