2.1Systemdesign characteristics
WZJ-31 device is composed ofhost, slave, display control panel, CT, and etc. The entire DCsystem adopts the collecting-distributing system of dispersedmeasurement and centralized management. With this design thought,the system is clear in composition level and easy and flexible torealize capacity expansion.
To monitor the insulationinformation, there is no need to inject any signal to DC system,and it has no bad influence on the DC system.
It is resistant to the adverseinfluenced caused by large grounding capacitance of DCsystem.
The intelligent transformerused is resistant to residual magnetism effect and can run reliablyfor a long term.
