4.1 Overview
This section describes the ADR111A/ ADR211A Single Pole IED settings, including the
protection elements and basic functions associated with the protection function.
Application data.
Describes the list of information that you will need to know about the protected equipment
before calculating the relay settings.
Relay Settings.
• List of settings that configure the IED inputs to accurately measure and interpret the ac
current input signals.
• Describes the Breaker Failure settings for Breaker failure on internal protection trip
• Describes all the over current settings and logic needed for protection for the over current
fault
4.2 Application Data
It is required to have the field data which is used to calculate the parameter settings which
has to be set in the IED. Hence the following inputs are required to calculate the parameter
settings in the relay.
• Highest expected load current.
• Current transformer primary and secondary ratings and Connections
• Expected fault current magnitudes for OC Faults
