WZJ-31 device is composed of host, slave, display control panel, CT, and etc. The entire DC system adopts the collecting-distributing system of dispersed measurement and centralized management. With this design thought, the system is clear in composition level and easy and flexible to realize capacity expansion.
To monitor the insulation information, 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 adverse influenced caused by large grounding capacitance of DC system.
The intelligent transformer used is resistant to residual magnetism effect and can run reliably for a long term.
