We're here to witness the FAT for the two 50 MVA power transformers per the approved FAT protocol. Is the test setup ready?
我们来见证两台50MVA电力变压器的工厂验收测试，按已批准的FAT大纲。测试准备 好了吗？
Yes, both units are connected. We'll start with the ratio test on all tap positions, then winding resistance, followed by the insulation resistance and dielectric tests. The test equipment calibration certificates are posted on the wall.
好了，两台都接了。先从各分接位的变比测试开始，然后绕组电阻、绝缘电阻和耐压 试验。测试设备校准证书贴在墙上。
The ratio deviation must be within ±0.5% of the nameplate. If any reading exceeds that, we stop and investigate. Also, I want to witness the oil sample being taken for dissolved gas analysis — that's a hold point.
变比偏差必须在铭牌的±0.5%以内。超了就停查。另外油样做溶解气体分析我要 见证——这个是关键点。
Understood. Let's proceed. First unit — ratio test starting on tap 1. Reading is 99.8% of expected. Well within tolerance. I'll call out each reading for your record.
明白。开始。第一台——分接1变比测试。读数是预期的99.8%。在允差内。我给你 一个个读数报，你记。
I've been recording. So far all within spec. After we finish all electrical tests, we need the temperature rise test — but that takes several hours. Can we do that overnight with data logging?
一直在记。目前都在规范内。电测试全做完后要做温升试验——那要几个小时。能 不能晚上跑，自动记录数据？
Yes, we can run it overnight with automated data acquisition. I'll provide you with the full temperature curve tomorrow morning for review.
可以，晚上跑带自动数据采集。明天一早给你完整温升曲线审核。
We've completed the functional test for MCC-06A. Twenty-three out of twenty-five circuits passed. Two issues: feeder 12 has a faulty relay and feeder 18's ammeter reading is inconsistent with the test instrument by 8%.
MCC-06A功能测试做完了。25个回路23个通过。两个问题：馈线12继电器故障， 馈线18电流表读数与测试仪表差8%。
Let me check. The relay on feeder 12 was damaged during assembly — we already have a replacement and can swap it in within the hour. The ammeter issue — was the CT ratio setting verified?
我看看。馈线12的继电器是装配时磕坏的——备件有，一小时内更换。电流表问题—— CT变比设定核实了吗？
Yes, the CT ratio is correct per the schematic. It appears to be a calibration drift on the ammeter itself. We need that replaced or recalibrated and retested.
核了，CT变比按图纸正确。应该是电流表本身校准漂移。需要更换或重新校准后 再测。
We'll replace the ammeter — faster than recalibration here. Both items go on the punch list. Can you conditionally accept the other 23 circuits while we fix these two? We'll demonstrate the fixes before end of day.
我们换电流表——比现场校准快。两项都列入尾项清单。能否有条件接受其余23个回路， 我们修复这两个？下班前验证给你看。
Acceptable. I'll note the conditional acceptance in the FAT report and will sign off fully once both punch items are cleared. Shipment release is pending full closure of all punch items.
可以。FAT报告中注明有条件接受，两项尾项关闭后我正式签字。发货放行须等全部 尾项关闭。
