Sound, causing short circuit obstruction. If not handled properly it will cause great damage.
After no-load test run is normal for 24h,Rosetta500 kV dry type transformer, it can be transferred to on-load operation, and the load shall be gradually increased from 25%, 50% and 75% by grade.

.What is the wavelength of oil immersed transformer?
After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite,RosettaOil immersed self cooling transformer, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.

Noise dispersion of dry-type transformer
After no-load test run is normal for 24h, it can be transferred to on-load operation, and the load shall be gradually increased from 25%, 50% and 75% by grade.
The noise of dry-type transformer comes from
Total quality assurance.After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
Rosetta.The switching power supply lacks one phase of power;
The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, and between the electromagnetic coil and the tap changer.
Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).
