SR 3.8.1.2 ------------------- NOTES -------------------

1. All EDG starts may be preceded by an engine prelube period and followed by a warmup period prior to loading.

2. A modified EDG start involving idling and gradual acceleration to synchronous speed may be used for this SR as recommended by the manufacturer.

Verify each EDG starts and achieves steady 31 days state voltage 2 3873 V and - 4580 V and frequency 2 58.8 Hz and : 61.2 Hz.

SR 3.8.1.3 ..... - -............ NOTES .................---

1. EDG loadings may include gradual loading as recommended by the manufacturer.

2. Momentary transients below the load limit do not invalidate this test.

3. This Surveillance shall be conducted on only one EDG at a time.

Verify each EDG is synchronized and loaded 31 days and operates for a 60 minutes at a load 2 2500 kW.
