For a generous approach, a standard of 1 kV per 1 meter is sufficient.
Ahah, it should work fine to start it! But the insulation resistance is still low; in cases of poor weather conditions (such as rainy days), it is still acceptable. If the weather is clear, the insulation resistance is low; it’s best to check and address the wiring of the motor cables.
Isn’t the standard that 1 KV corresponds to 1 megohm? It can be activated
Start it without any problems, run it for a while, and check the changes in insulation resistance.
It can be started; it is recommended to use a value of over 60 megohms for starting
