Hi, when it comes to Transformer Oil testing, there are some parameters that we need to consider but i don't understand their definitions and i can't find their explanations online, so may someone plz define these terms for me that what these terms actually mean? the terms are as follows:

Initial Stand Time

Rate of rise of test voltage

Intermediate test time

Intermediate stand time

Maximum duration of selected sequence

Standard Deviation

Here's a starting point. Note the standard test methods such as ASTM xx. If you search for the details of those individual tests you can find what they test.
