NHS England HTM 06-01 Electrical Services Supply and Distribution (2017 Edition) 10.17-10.30: HV protection design, grading and review on network change

Protection should disconnect only the faulty part with minimum disruption and be consistent with the distribution strategy. Grading should achieve discrimination by time separation or by unit protection, and the protection and grading should be reviewed whenever the HV infrastructure changes. Where the secondary supply includes HV generators, automatic network reconfiguration control after HV faults is essential, tied to the clinical and business continuity assessment.
