Desired power factor You can use this parameter to set the power factor, which the transformer has under normal operating conditions.
  • Page 96 If the tap difference is greater than the set maximum tap difference to the mas- ter, the follower blocks and no longer attempts to attain the master's tap posi- tion. After the set delay time for parallel operation error messages has elapsed, the follower issues the Permitted tap difference to master exceeded message.
