FAQ

1.What phenomena are abnormal in power transformer operation?

(1)severe oil leakage(2) the oil level is too low.(3) oil level is too high(4) no oil level can

be seen on the oil storage tank and casing(5) transformer oil carbonization.

2.What are the dangerous conditions when the transformer is running?

(1)oil storage tank and safe airway injection(2) excessive change in oil color, the

presence of carbon in the oil(3) severe oil leakage causes the oil surface to drop below

the indicated limit of the oil level gauge.

3.How to install outdoor power transformer?

The height of transformer piers installed on the ground is generally 0.5m, and a fence of no less than 1.7m should be installed around them, and warning signs should be hung in obvious places.
