High level of security:

Reduce the contact voltage and the leakage current of the grid to the ground, effectively control the direct leakage current to the heart, and reduce the danger of personal electric shock to a small extent.

The insulation monitor in the system can monitor the insulation status of the system in real time, and give an alarm in time when there is an insulation fault to remind the staff to eliminate the fault in time.

Continuous and reliable power supply:

The live conductor at the power end of the IT isolated power supply system is not grounded, even if a single-phase grounding fault occurs, it can only form a loop through the system to the ground capacitor, and the fault circuit impedance is large and the fault current is small, so it is not necessary to cut off the power supply in time to prevent electric shock, so as to maintain the uninterrupted power supply.

The power supply is only required to be cut off in the event of a secondary ground fault, ensuring the continuity of the power supply.

Strong fire safety:

The insulation monitor also detects the overload of the system and the temperature rise of the transformer, and alarms immediately once there is an abnormality, reducing the electrical fire accidents caused by system heating and leakage.
