Andre,
The standard 61000-4-5: 2006 says that decoupling networks are required to
provide sufficient decoupling impedance to the surge wave so that the specified
wave may be applied on the lines under test. With this alternative test
method, I don't think you can say that you are decoupling
Greetings.
Is it a requirement in Canada, or any other country, to which industrial
machines with large AC motors (such as 25hp) must be soft started using a
Frequency Drive/Inverter? If this is true, where do I find this ruling?
Electric Code??
I have heard rumor of this in the past. And
Look at hiring?

Dear Sato,
Thank you. Yes, the standard suggests a method for currents over 200A. However,
we are speaking of a current of about 70A, in which the lab does not have a CDN.

Dear all,
We have some products with a current higher than the Surge test CDN from many
labs in our region can withstand.
So, we found a lab that does an alternate Surge test.
Instead of connecting the product to the CDN, they connect it directly to the
power supply.
In the output of the CDN,
