1. There is no fault in the transformer itself. You can check if there is a problem with the non-electrical protection device itself and if it may be malfunctioning.
2. Protection configuration problem, investigate the phenomenon. If the phase AB fuse is blown, there should be an overcurrent, but the overcurrent does not act. Check again if the protection setting value is incorrect. .
3. If a short circuit is reported on the low voltage side, whether between phases or to ground, it will not only trip. A phase or three-phase short circuit will cause overcurrent, causing the protection to trip, so you should focus on checking the low voltage side.
Didn't the pressure plate blow when the 4.35 kV protection had no tap? She still hasn't moved. It should have triggered the high and low voltage tests.
5. The value of tcurrent transformer temperature can be queried
1.5 MW wind turbines typically use 1600 KVA, but I seem to have seen 1800 KVA in this wind plant
p >0.75 MW 800KVA
Our company manufactures 2250KVA for 2MW
We have never manufactured 1800 and cannot give it to you, let alone yours is only 10KV
