(OP)
hi,
can anyone tell me how to determine the deadband of the tap changer correctly, given that the tap changer is +/- 12%, +/-6 steps (12 steps) 1%.
your help is greatly appreciated.
Many thanks

RE: deadband
By the way, you indicate +/- 12% (a 24% spread) with 12 steps of 1%. This doesn't add up!

RE: deadband
If it is possible to calculate the absolute difference between upper limit voltage and the reference voltage, lower limit voltage and the reference to define the deadband limits, ignoring any hystersis term as described in the following link?

RE: deadband
With a 2% step size, I'm not sure I would want to double it to get the recommended deadband. The taps may never change with that wide a deadband!
To start you might want to set it at 1.5 times the step or 3% and then monitor the number of operations in a month. Based on thhe number of operations, you can then adjust to a higher or lower value.
