Does the voltage rating of the Current Transformer matter if you are measuring on the neutral side?

Table 7 Basic Impulse Insulation Levels for Current Transformers
Nominal Voltage (kV) BIL and Full Wave Crest (kV)
0.6 10
2.4 45
etc.
Suggestion: As electrical engineers, experts, specialists, etc., the standards are good to have accessible.
Next, for example, 600V CT may have BIL 10kV
however, when applied over conductor or cable insulation, this insulation BIL counts and adds to the CT BIL. Therefore, on the 69kV system voltage the CT over an insulated cable can be 600V with BIL 10kV under an assumption that the cable insulation would provide the remaining 340kV BIL to agree with Table 7 CT BIL 350kV.
