AVR Time Setting

[SMB1]

Hi everybody

I have two time setting of the AVR relay T1 & T2 Type SPAU341C. I want to consider the operating time mechanism of the Tap Changer and then add it to the time setting.

My question is how much time tap-changer does need to perform one operation?

Note that I have 69/13.8KV Xfmr.

Thank you

5 seconds, more or less

Can't you measure the operating time of each operation?

If you have any interposing taps, it will take longer to tap when the interposing taps are in operation.
