Insulation withstand

viltage test

Insulation resisitance test:

To test the insulation value between total positive electrode and housing, between total negative electrode and housing (HIOKI safety specification table).

Pressure test:

Pressure machine is in the normal connection with the positive electrode of the system and in ground connection with the housing.

Pressure machine is in the normal connection with the negative electrode of the system and in ground connection with the housing.

Pressure machine is in the normal connection with housing and in ground connection

with the positive electrode of the system.

Pressure machine is in the normal connection with housing and in ground connection

with the negative electrode of the system (HIOKI safety specification table).
