Protection Setting Studies

These should be carried out on new power systems such as a new industrial installation, but also done for modifications to existing power systems. Judgement needs to be applied in such cases to determine what parts of a full study are needed. The full protection study comprises:

• Establish system data
• Fault level calculation as necessary
• Liaison with interested parties
• Produce setting schedule
• Prepare drawings and co-ordination graphs
• Preparation of narrative on settings and recommendations
• Preparation of full report, a controlled document
