The Power Profile is a specific set of PTP rules for applications in high-voltage and power grids, defined in IEC 61850-9-3 and IEEE C37.238.

It guarantees time synchronisation in the range of about 1 microsecond between substations, needed for synchrophasor measurements (PMU) and grid protection.
